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?"
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 used my online family tree at Ancestry.com and manually counted the number of ancestors for which I have documented a first and/or last name. I then created the following chart in Microsoft Excel and used the built-in formulas to calculate my "ancestor score." I have hidden a few of the columns in the image below for ease of viewing.
I have spent the majority of my research time over the past few years concentrating on documenting the connections that my family has "collected" over the years. I'm finally starting to make my way back through my great-grandparents and have a 100% score through my 2x great-grandparents. I was very happy with my scores of 84 percent for my 3x great-grandparents and 52 percent for my 4x great-grandparents.
I still have quite a bit of work to do in researching my family tree. One of my research goals for 2014 is document two additional 3x great-grandparents, which will bring my 6th generation "Ancestor Score" up to 87 percent.
