I am related to Oza A. McKnight (not Oza Collins McKnight) and his wife Rosannah thru their son Andrew Jackson McKnight who md. Martha Ann Wood. "Lanthrip" was Rosannah's first marriage name. Her maiden name is Rosannah Esmond. I think she had one son (Volney Lanthrip) when she married Oza A. McKnight and the two of them had eleven children, seven daughters and four sons.
