This is amazing. My ancestor, Thomas Bennett, b. 1811 in "England", married in 1848, Phoebe Creswell, in Iowa. My Thomas died en route to Oregon in 1852. He purchased property in Iowa in 1846, the deed of which says, "Thomas Bennett, of Montgomery County, Ohio". I've yet to find a match in the 1840 census. Sorry we're probably not related - I'd love to find my Thomas Bennett's parents.
