I got this idea from Genea-Musings and Family Tree Magazine and thought it would be interesting.  Charts and graphs are fun to make, not to mention this entire blog post took about 15 minutes to do.

Here’s what I did:
1.  Listed the birthplaces of all 16 2nd great grandparents.  For simplicity, I’m used my Mom’s 16.
2.  Made a pie chart of said ancestors and birthplaces.

Here’s what it looks like:

All of my Mother’s 2nd great grandparents were born between 1820 and 1854 and all of those born overseas, died in America.  I’m a little surprised at how many ancestors at that time were already in America.

This is what it looks like if I include the individual states:

Here’s the data set (my Mom’s 16 great-great grandparents):

Harman A. Updegraff – Pennsylvania
Margaret Miller – Pennsylvania
David H. Davis – Wales
Catharine Annie Harris – Wales
William T Hutchinson – Pennsylvania
Ann Marie Jamison – Pennsylvania
Egbert T Zillifro – Pennsylvania
Sarah Ellen Willis* – Pennsylvania
William W Duncan – Ohio
Jennie Salina Ford – Ohio
James Rostrom – England
Annie Nora Slave – Ireland
William Murphy – Ireland
Katherine Aspery – England
John Richards – England
Ann Williams – Wales

*Unconfirmed -some sources indicate this may have been a Seneca Indian named Rebecca, also likely born in Pennsylvania.
