Does anyone have a connection with Oliver McIllduff (my 5th g. grandfather) b. Oct 1740 Down, Ireland, d. 1799 in Pennsylvania, m. Sarah Agnew b. 1750 Antrim, Ire, d. July 1831 in PA. They had 10 children. The first two, Oliver b. 1766 and David (my 4th g grandfather) b. 1767 in County Down before going to America. When they came to America they changed last name to just Duff.
Would be great to find parentage of Oliver McIllduff and Sarah Agnew---
Sorry I don't have the parish in County Down---
