So I decided to give it a try myself:
|Generation||Potential Ancestors||My Identified Ancestors|
|2x Great Grandparents||16||16|
|3x Great Grandparents||32||32|
|4x Great Grandparents||64||47|
|5x Great Grandparents||128||38|
|6x Great Grandparents||256||34|
|7x Great Grandparents||512||41|
Grand Total: 222 out a possible 1022, or just under 22%!
Darn. I started out so strong! 100% out to my 3x great grandparents! But the numbers really started to dwindle as I got further back.
In particular, I noticed my mom's side dropped out of the calculations pretty quickly, other than my direct maternal line which I've put a lot of work into. But all those English lines, they go back to 1830 or so and then things start to get challenging! My dad's side, on the other hand, is all French Canadian, so those lines tend to go back to the 1600s pretty easily.
But I'm not discouraged! I'm still thrilled by how much my tree has grown in recent years, and am excited to see the new directions it will take in the future. (I recently learned I'm part German! Who knew?) Perhaps I'll fill in this table again a year from now and see how far I've come.
