Background

This Free-Space page is intended to collect together my ideas for WikiTree add-on functionality, in response to a recent G2G post by Chris Whitten:

• G2G Posts:
  • Would you collaborate on a Browser Extension? by Whitten-1.
  • Genealogy Tree Visualization by Więch-13 (Topola Genealogy Viewer).

Ideas

• Identify earliest person profile matching certain criteria
• Provide a placeholder for a group of person profiles
• Visualise how a person profile is robustly connnected to the public tree
• Visualise the shape of the relationships between a large group of inter-related person profiles without being overwhelmed wirh the details
• Identify candidates for connecting to a One-Name-Study by virtue of time and place
• Export and import genealogy data through a GEDCOM Gateway
• Visualise your direct connection to deep Ahnentafel ancestors on each surname line

WikiTree Apps

WikiTree API Demo

• Apps.WikiTree.com - Demo
• Converting Spread Sheets to WikiTables

Ahnentafel Charts

There are a number of existing options:

• Excel/VBA tool to manage ahnentafel and generate tree
• Ahnentafel Explained (G2G)
• Ancestor List for Stephen Adey (WikiTree 7 generation Ahnentafel list)
• WikiTree Compact Tree for Stephen Adey (up to 8 generations on one page, with Ahnentafel numbers)
• Ashley's Ancestor Listmaker App - ahnentafel list
• [https://www.wikitree.com/wiki/Space:Benjamin-1380_Ahnentafel Ahnentafel in wikitable format

Summary Chart

Google Sheets based chart

The following spreadsheet represents my Ahnentafel (Ahn) ancestoral tree numbering, based on an unverified/unsourced data tree in FamilySearch.org. Each grid cell is normally empty (white) or coloured light blue or pink to represent a male or female individual, since by definition it contains a reproductive family tree. The Ahn numbers have been arranged in the grid so that (in each row) the next number in the row is exactly double the number to its left, and all but the first number will be even. With the classic European surname naming convention, this results in everyone on a horizontal row having the same surname.

The first number in a row will be odd, and represent a female married (or coupled) to the male vertically above her in the grid. By convention, the exception is the number 1 (in the top left corner) which represents the 'unmarried' root of the tree, who can be male or female. All the remaining numbers in a row will be even and represent male ancestors. For any woman, her father will be immediately to her right, with her grandfather to his right, and her mother and grandmother below them. Thus a vertical box can be drawn round each couple, with their descendent branch starting to the left of the man.

The Ahn number should be accompanied by the name of the individual, and normally their birth and death dates, to help identify them in a sequence of individuals with similar names. Ideally each person cell will contain a link to their profile, to access other information (like their marriage date) which is often included in a tree. Since the Ahnentafel grid should be wide as necessary, to include all known direct ancestors, it is important to minimise the number of unidentified ancestors. It will be most useful if the grid only contains one placeholder for each direct brickwall ancestor, thus many brickwalls will be represented by a black outline round the light blue and pink blocks containing their Ahn numbers but no other information. It is important that this grid can be generated automatically, by a WikiTree Extension App, so that new persons and revised brickwalls are easily added from the WikiTree database.

wikitable based chart

WikiTree supports the Wikimedia tables built using class=wikitable. The following represents a first attempt at reproducing the Ahnentafel spreadsheet using this table functionality. It quickly became clear that the useful black outlines would be hard to reproduce on a larger grid.
