I am looking for descendents of HENRY HARRISON DEWITT who was born in Chemung County, New York, July 16, 1814 and in 1818 his parents Charles and Lydia De Witt moved to Richland County, Ohio, and thence in 1830 to Delaware County, OH. He married March 8, 1835, to Mary M. Caulkins, who was born in Chenango County, New York, March 1, 1812, a daughter of Ithel and Polly (Terrell) Caulkins. In 1852 he came to Iowa and lived three years in Cedar County, moving in 1855 to Black Hawk County. They had 10 children. I have no names of children.
