I am researching my husband's family. His ggg-grandfather Jacob Isenhart married his ggg-grandmother Anna Catharine Glassford on 26 Oct 1826 in Preble Co., Ohio. His brother William Isenhart married Mary Glassford on 20 May 1830 in Preble Co., Ohio. I can not find anything on the Glassfords. Any help would be appreciated. Thanks, Nikki
