Andrew KOPP
Margaret A. GEESEY
In the case of both Andrew and Margaret, birthdates on their tombstones are out of line with their birthdates in the censuses.  As the more first-hand and more contemporary records, the censuses should be given more weight than the tombstones (see this page for a discussion of the reliability of tombstones and death certificates with regard to birthdates).

Living three households from Elizabeth KOPP (æ 10, b. PA, living w/Elisha FULTZ family), who is living four households from Andrew's presumed brother, Jacob KOPP.  Given the difference in age between Andrew and Margaret, it is likely that Andrew had a prior wife, which makes it likely that ten-year-old Elizabeth is Andrew's daughter by that wife.
