Many of the responses to this task were sketchy and some had a lot of blanks, so I should feel lucky that at least I have names and locations for all of my great-great grandparents. I am needing to find some marriage dates and locations. (Most of mine were estimations based on the births of their oldest children.) I was surprised to find so many of them being born in New York - I'd have thought Pennsylvania or Maine.
Oops, I just noticed that I should have had 4 for Kentucky (blue) instead of three, so New York doesn't have the most. (I guess the total should add up to 16 if you are listing your 16 g g grandparents, right?)
Why don't you try this and see how many of these ancestors you can find. [Hint - you might use an Ancestral Name List from your software for this. However, if you use Family Tree Maker, it may not be available - I couldn't find it on mine; had to cut and paste to a Word doc.] The graph was created using the chart generator from Kid Zone per Randy's suggestion.
Good luck and happy genealogy hunting.
