Hi - I do not have a Hannah that I know of but she could be a collateral
line. My John C and Mary Graham lived in Cass Co for about 8 years from 1862 to
1869. They were in Iowa in 1860 and 1870 as I found them in the census. They
went to Cass Co. and three children were born there. They must have gone
there because relatives lived there, possibly due to parent's illness, the Civil
War or ???.. John had a brother Samuel and he and his family are thought to
have gone too. They are my huge brick wall!!! Good luck. Sheilah
