I have the marriage record for Helen S. Cowen & Francis G. Stanley, married in Sycamore, DeKalb County, IL, 21 Sep 1862, but no trace of them after that. Helen is with her parents, Theodore Smith Cowen & Marilla, in the 1850 and 1860 Census for Sycamore. I have not found any census records for Francis G. Stanley. The Cowen family moved to Portage Co., WI, and then Marathon Co., WI before 1869. Theodore & Marilla are my gg-grandparents.
