Thanks! Catherine's record is in the records of St Paul's Lutheran Church of Shenandoah, VA in Page Co. It gives her birthdate and that she was sponsered, but gives no baptism date.
If there are no errors on my part, which does happen, her children with Jacob Foltz were: Jonas (1798), Ruben (1800), Eve (1804), Rebecca (1806), Daniel (1808), Elizabeth (1810), Susanna (1811), Catherine (1814), Hel(l)ena (1816), and Jacob (bef. 1825). I've got marriages for all of these children except Jacob.
