1) Determine how complete your genealogy research is. For background, read Crista Cowan's post Family History All Done? What’s Your Number? and Kris Stewart's What Is Your Genealogy "Score?" For comparison purposes, keep the list to 10 or 11 generations with you as the first person.
2) Create a table similar to Crista's second table, and fill it in however you can (you could create an Ahnentafel (Ancestor Name) list and count the number in each generation, or use some other method). Tell us how you calculated the numbers.
3) Show us your table, and calculate your "Ancestral Score" - what is your percentage of known names to possible names (1,023 for 10 generations).
I did this challenge back in January 2014 and so to update my chart, in Family Tree Maker for Mac, I ran a new Ahnentafel report for ten generations of my ancestors and counted the names. I then updated the spreadsheet that I had created the last time I did this.
My "Ancestral Score" is 468 known names to 1,023 possible names in ten generations for a percentage of 45.7%, an increase of 3.1% (32 names) since the last time I calculated this.
The changes are on my mother's side, partially because of work I did on my Townsend line. (See Surname Saturday ~ Townsend of England, Massachusetts and Maine). This is a colonial New England line, so I should be able to add to this branch with not too much work.
