Welcome to genealogy Brad! It's really great digging into your family's history.
My great great great grandparents with George and Elizabeth TUVELL. I've traced them from Huntington, Ross County, Ohio to Cerro Gordo, Piatt County, Illinois where my mother was born. We have lots of TUVELL family members in Ohio and Illinois.
Here's my genealogy database, just click on this link:
