I found Henry and Sara in the 1860 Virginia (WV) Census. Ohio County, Township Clinton, P.O. They both were 50 years old and according to this census they were both born in Maryland. Only 3 children were listed: Henry 19, Zacheus 13, and Mary E., 8. I have located two Henry Greers in Maryland Census Records, Charles County and Baltimore County in 1830 and 1840. I'm still researching the Maryland Greers, but I'll let you know what I find.
