Gloria: I stumbled across two more Blosser-Grove marriages while looking for something else. They are from the 1957 Beery Family History. I suspect this is a different Grove family than the one you are trying to track, but is probably related. Didn't know if you already had them.
Martha Blosser, daughter of Isaac Blosser (c1777-1845) and Martha Beery (b.1787), married Oliver Grove, son of John Grove who emigrated from Pennsylvania to Fairfield County, Ohio, in 1827. They had 7 children. The children are not listed in book.
Noah Blosser (b.Jan 1830), brother of Martha, married Matilda Grove, sister of Oliver, on June 10, 1850. They had 9 children, but again book does not list them.
