Do you have any information that goes back from Martha Dickey. I am trying to trace the parent's of John. I have a very undocumented source that their father's name could be Thomas.
From what I know, John Dickey married Margaret Longcor in 1819 in Ohio. In 1835, John purchases three parcels of land in Elkhart County where he lives with his family in the 1850 census, they are actually enumreated in Clinton Township of Elkhart County. As of 1853, the John buried in Jackson cemetery is dead and the family has moved to Iowa by 1860, where the oldest son Solomon, his mother and two sisters are with him.
John is supposed to be born in PA, but I can't find a record which helps me to verify where and what his parent's names are.
