Individual Details

The Indiana database shows the early marriage of Jane Harmon to William Crist on 10 May 1816 in Franklin Co. FamilySearch.org family tree shows a son - Jacob Crist, b. 1818, as well as a James, b. 1817. No proof of these sons.
Then Robert Mitchell married Jane Harmon - there are two dates, Jan 26 and Jan 28 of 1819. It would seem that their was a divorce as Crist also went on to remarry. The image on FamilySearch, shows that the license was issued to Robert Mitchell and Jane Harmon on 26 Jan 1819. Charles Crabb, JP, married them on the 28th of Jan.
Chesley Wray married Jane Mitchell as his first wife.

There is a descrepancy in the surname - it was Wray in the marriage record, but Ray in the censuses.
