Getting Started

One Page Genealogy is the perfect site to create a compact tree chart of your family with a few quick clicks.


Create Your Chart

One Page Genealogy allows you to create three different types of charts.

Note: You can always click the "Download New File" button at the top of the page to restart the chart creation process.

My Tree

  • This option will automatically put you in as the root of the tree.

  • Select how many generations you want to show by selecting a number from the dropdown menu.

  • Select which direction you would like your tree to go:
    • Ascendancy: creates a tree with each generation being the parents of the last generation.
    • Descendancy: creates a tree with each generation being the children of the last generation by spouse.
  • If you have not already authenticated with FamilySearch:
    • You will be prompted to do so through FamilySearch login.
    • This is necessary because all the data for your tree is pulled straight from FamilySearch.
  • If you've previously authenticated with FamilySearch through One Page Genealogy, simply press "Submit" to generate your chart.
  • Because of the large amount of data, may take a few minutes for the chart to appear.
  • Expect longer loading times for larger numbers of generations.

Other Tree

  • Enter the FamilySearch id (XXXX-XXX) of the person who will be at the beginning of the chart or leave it empty to start with yourself.

  • Select how many generations you want to show by selecting a number from the dropdown menu.

  • Select which direction you would like your tree to go:
    • Ascendancy: creates a tree with each generation being the parents of the last generation.
    • Descendancy: creates a tree with each generation being the children of the last generation by spouse.
  • If you have not already authenticated with FamilySearch:
    • You will be prompted to do so through FamilySearch login.
    • This is necessary because all the data for your tree is pulled straight from FamilySearch.
  • If you've previously authenticated with FamilySearch through One Page Genealogy, simply press "Submit" to generate your chart.
  • Because of the large amount of data, may take a few minutes for the chart to appear.
  • Expect longer loading times for larger numbers of generations.

From a Gedcom

  • Once you have logged in, click "Read Gedcom File" if you want to create a chart from a Gedcom file you have on your computer.

  • Select your Gedcom file using the window that pops up and click open.

  • Choose id of the person who will be at the beginning of the chart.

  • Select how many generations you want to show by selecting a number from the dropdown menu.

  • Select which direction you would like your tree to go:
    • Ascendancy: creates a tree with each generation being the parents of the last generation.
    • Descendancy: creates a tree with each generation being the children of the last generation by spouse.
  • Click "Save Chart" to create the chart. It may take a few minutes for the chart to appear.

Explore Your Chart

Now you have your chart on the page, but maybe it's a bit too big to see all of it.

  • Zoom in and out: scroll middle mouse button, or use the corresponding buttons on the right side of the page ( to zoom out, to zoom in).

  • Pan around: left click and drag the chart.

  • If you get lost, you can always use the Recenter and Find buttons on the side panel to find yourself or someone else by ID.

  • Click the arrows on the top of the screen. to rotate your chart clockwise or to rotate counter-clockwise.

  • Click the download button () to download your chart as a PDF file.

  • Click the ruler button () to show a ruler along the top of your chart that can be used to help you size your chart.


How to Use the Detail Viewer Window

Clicking on a box will bring up the detail viewer window.

  • The first thing you'll see is a window showing what the box looks like at full size. This can be handy if you are zoomed out.

  • Aside from a close up of the box, the information for the people in the box is also displayed in its full format - including pictures where possible.

  • Identification codes can be found at the top of the window.

  • There are also a few handy buttons on this page:

    • Click "View on FamilySearch" to view the person on FamilySearch if possible.

    • Click "View on Virtual Pedigree" to view the person on Virtual Pedigree if possible.

    • Click "Set as Root" to redo your chart with this person as the primary box.

    • Click "Collapse" if you don't want ancestors/descendants of that individual to be shown. Clicking this can reduce the size of your chart.

    • Click "Expand" on a previously collapsed box to undo collapsing it.

    • Click "Add Child (Parent)" to add a custom person beneath this one in the tree. See the features tab for more information.

    • Click "Edit Person" to edit the information for the person. These changes WILL NOT be reflected in FamilySearch or the source GedCom files.

      • In the edit pane, you can change the information on any given individual simply by changing it in the pane.
      • When you are done editting, press save to save the changes to the chart. Press close to stop without making changes.
      • Note: editting will not allow you to add or remove a spouse from a non-custom person.
    • Click "Remove Person" to remove a custom person or empty box. See the features tab for more information.


Edit Your Chart

There are a few things you can do to edit how your chart looks.

Changing Chart Style

  • Click "Styles" at the top right of the page and then choose the style you want.

    • All of these options will change the style of every box in the chart.

    • The upper options focus on ascendancy charts, while the lower options are configured for descendancy charts.

Changing Chart Color

  • Click "Colors" at the top right of the page and then choose the style you want.

    • All of these options will change the style of every box in the chart.

    • These options won't change the shape or size of the box, but will change the color.

    • In bordered boxes, the color you choose will be on the border, while the interior color will be just a few shades lighter.

Changing Chart Options

  • Click "Options" at the top right of the page and then choose the style you want.

    • These options add useful features to your chart.

    • Showing/Hiding empty boxes will put in empty boxes where you are missing people in your tree.

      For ascendancy-style charts, you may choose either to show all of the empty boxes, or just the first missing generation.

      Only the first missing generation is shown for descendancy-style charts.

    • Highlighting duplicates changes the color on boxes that likely correspond to the same individual to make copies easier to spot. These color changes can be overriden manually, or by selecting a chart color style.


How to Use the Ruler

One Page Genealogy features a ruling feature accessible by clicking the ruler icon on the top bar.

  • To begin, press the ruler button (). A smaller window will appear that will allow you to choose your print dimensions.

  • The initial dimensions are the dimensions on your chart as is. You can change those, however, to be whatever you want.

  • The dimensions that you input indicate that OPG should treat your chart as if it were Width x Height big.

  • After entering your dimensions and pressing 'save,' the ruler will scale with your chart to show you how many inches long your chart is.

  • by zooming your chart in and out until the ruler's inch is roughly the same size as an actual inch, you can get a feel for how big your chart is probably going to be.


How to Save and Upload Your Chart

To save your chart, simply press the save button () on the top bar and choose where you want to save it. One Page Genealogy charts have a .opg extension on them for easy finding.

To upload your chart, simply press the upload button () on the top bar and find the .opg file you would like to upload. Then press the 'open' button.


How to Print or save as a PDF

Simply press the download button () on the top bar to save your chart as a PDF.

You can then take the downloaded PDF to a nearby print service center.

Features

Here are the details for the tools that we offer you in One Page Genealogy


Chart Styles


Ascendancy Chart Styles

These are designed for looking at ancestry.

  • Full Detail Style

    A good chart style for most things. Most of its boxes are oriented for compact spacing, and contain as much information as possible.

  • Family Reunion Style

    This style is designed for wall charts to display for family gatherings. It features larger boxes than most other styles, and can handle many generations.

    Also build for a normal page, this chart uses a more compact style to fit in some extra details. Fits 6 generations.

  • 11 x 17 Style

    This is the premier style for descendancy charts. It looks great on most charts.

    This style is for creating charts with many generations, scaling the box sizes to fit your chart's needs.


Color Schemes


Branch Schemes

  • Color by Branch - Pastel (Default)

    A solid color scheme that helps distinguish branches in standard genealogical colors.

  • Color by Branch - Bold

    A new flavor of branch coloring featuring bolder variants of the standard colors.

  • Color by Branch - Greyscale

    A greyscale branch coloring system.

Generation Schemes

  • Color by Generation - Warm

    A rotational color-by-generation scheme that uses red, orange, yellow, and purple as its colors.

  • Color by Generation - Cold

    A new rendition of the old monochrome style. Uses blue, green, light blue, and light green.

  • Color by Generation - Vibrant

    A simple color scheme that uses all sorts of different colors.

  • Color by Generation - Wood

    A slightly-stronger-than-sepia color scheme focusing on pleasant tans and browns that are appealing and easy on the eye.

Other Schemes

  • Child Heat Map - Red & Blue

    Boxes are colored in based on the number of children they have. Dark boxes have few children, lighter boxes have more.

  • Color by Gender

    Men are blue. Women are pink. Gray is unknown...

  • X Chromosome Contributors

    A newer feature for our users, this style traces your X chromosome. Grey boxes are non-contributors, while colored boxes represent those of your ancestors whose genes contributed to your X chromosome.

  • Color by Country

    Color codes your ancestors based on nationality.

    The original colors are generated at random, but can be changed from the sidebar that pops up.

    Use on Ascendancy Charts for best results.

  • Greyscale

    It doesn't get simpler than black and white.


Custom People NEW

This feature allows you to add custom people to the tree in the next generation. For ascendancy-style charts, this means you can add a parent, and for descendancy-style charts it means you can add children. It is designed to help fill in generations for descendancy charts where some people that would otherwise be on the chart are still be living.

Due to FamilySearch's privacy policy, One Page Genealogy cannot show information for living people. However, you can create the boxes for these people manually to help you create the tree that you want. This will enable you to create the nodes for the people they want without creating multiple private copies of those people in FamilySearch, and is ideal for filling in the lower generations in descendancy-style charts that may include living persons. It is encouraged that you use this feature for living people. This feature is discouraged as a means of adding information for deceased people, as the information is not saved to FamilySearch. Please use FamilySearch to add information about deceased persons. If you are still unsure about when to use this feature, please review the following guidelines and warnings:

  • Children WILL NOT added to FamilySearch.
  • Children WILL NOT added to uploaded GEDCOM files.
  • Children WILL NOT be viewable on FamilySearch or on Virtual Pedigree.
  • Children WILL NOT be preserved if you leave/refresh the page before saving your chart.
  • Children WILL be preserved in saved charts. Simply upload the chart using the upload button on the top bar.
  • Children WILL NOT be transferable to other charts. They exist solely on the chart for which they are created.
  • If you add children, save, and then leave the page, the children will not be present in your chart until you upload the saved data
  • The bottom line is that One Page Genealogy is designed for viewing and styling charts, but is not designed as a method of building one's family tree.
  • A button has been added to the creation page that will allow you to view the parent's profile on FamilySearch and make permanent children there.

Creating Custom People

  • In the detail viewer, click the Add Child button (Add Parent for ascendancy-style charts).
  • Fill in the information of the new person, leaving unknown entries blank.
  • Dates and place names should use spaces rather than commas to separate information
  • Press the Create button to add the person to the tree.

Editing Custom People

  • You can edit the information for custom people the same way you would do it for any other person.

Removing Custom People

  • In the detail viewer, click the Remove Person button. The person should be removed from the tree.

Chart Statistics NEW

This feature gives you more information about your chart and family tree. A quick list of the available statistics and what they describe is included below.
  • Total People: The total number of people included in the chart.
  • Percent Male: The total number of males in the chart.
  • Percent Female: The total number of female in the chart.
  • Percent Unknown Gender: The total number of people in the chart whose gender in not specified.
  • Estimated Percent Full: An estimation of how full your chart is. Compares the number of people in your chart with the number of people that should be in your chart. Because trees effectively double in size for every generation added, this tool is most effective on charts of 8 generations or less. In descendancy charts, 4 children per family per generation is used as our (conservative) standard for calculations. Actual percentages for descendancy charts will vary.

FAQ's/Support

We're still building this page, so if you've had a problem and it isn't listed here, please let us know so we can add it to the list. Thank you for your help!


My Chart is Wrong

One Page Genealogy obtains its information from FamilySearch/Gedcom files.

If your chart is different than you think it should be, check FamilySearch or your loaded Gedcom and make sure that the data is correct there.

Different Spouses

By default, One Page Genealogy uses the preferred spouse indicated on FamilySearch or the first listed spouse on Gedcoms files.

Different Names

By default, One Page Genealogy uses the primary name from both FamilySearch and Gedcoms files. Changing the file will allow you to get the correct information

My Chart Takes a Long Time to Load

One Page Genealogy has to download its information from FamilySearch. The larger your chart, the more we have to download.

To speed up your loading time, you can do one or more of the following:

  • Use Fewer Generations

    Each generation is exponentially larger than the last. If you don't need that last generation, try loading fewer generations.

    By default, we download 8 generations, but you can adjust that number both up and down. 8 generations (255 people for a full ascendancy chart!), but should only take a couple of seconds.

    If you are trying to download more than 11 generations, it may take some time, so be patient. A full 20 generation chart might take a few minutes.

    Descendancy charts often take far longer per generation to load than Ascendancy charts since each generation includes many more people. Expect a significant delay when loading more than 5 generations. A full 20 generation descendancy chart will take a while.

  • Check Your Internet Connection
    • If nothing ever seems to load at all after a few minutes, your internet connection might be blocked or significantly slowed.

    • Online games, video streaming services, and advertisments tend to hog your Internet connection and can significantly slow OPG

    • If your internet connection appears to be in order and there is still nothing loading, please feel free to contact us.

My Chart Experiences Lag When I Drag it Around or Zoom In/Out

One Page Genealogy uses Scalable Vector Graphics (SVG) to create your chart. These tend to be nice and fast, but there are some limits.

Most charts should move fairly fluidly, but will become a little bit harder to move depending on how many boxes you have on screen.

If you have 11+ Generations on screen, it is likely that you will start to experience some lag. Try zooming in to reduce the number of boxes on screen, since rendering all of those boxes slows your computer down.

I Clicked "Submit" For a New Chart, but Nothing Happened

Wait a few minutes before you panic. When you upload a chart, One Page Genealogy also uploads the pictures associated with your ancestors. sometimes these pictures can interfere with normal operation if they are still being loaded while you are trying to do other things like load up a new chart.

Where Are My Pictures?

The information for your chart may include some pictures that will render in the boxes alongside all of the other information about your ancestors. Often, these pictures will take a moment or two to load while they are being downloaded into OPG. Pictures should start to be added to your chart within a few seconds of being downloaded. This time will increase as the number of pictures needing download increases.
