I have been researching my husbands family. His gr. gr. grandmother was a Therese Bihler, b. 29 Aug. 1792 in France. She married Francois Joseph Bissler 15 Jan. 1823, They immigrated to USA ca. 1847. She died sometime between the 1850 and 1860 census but I have not yet found where or exact date. Her husband and children settled in the Stark-Portage Co. area of Ohio. Therese's parents were Joseph Bihler and Catherine Haffner. Is this a possible connection or of any help to you.
