I believe they were Jacob W. Hoagland and Alathier Jiles/Giles/Childs/Chiles. Alathier first married Isaac L. Fowler and had another family, which my gggrandmother Malinda (m. William Carpenter) was born into. I do not believe she made the migration to Iowa and Isaac Fowler divorced her in 1850. I believe that Jacob W. Hoagland was married before Alathier also. On 25 Mar 1850, Alathier married Jacob Hoagland in Wayne Co., IN. I cannot find it now, but I did see an index entry to the marriage of Eliza Alathier Hoagland to Owen Hughes Jackson and it said her parents were Jacob W. Hoagland and mother was Alathier (some spelling of it) Jiles.
