I am related via John McGuffin and Mary Price from Dungannon, Tyrone as our common ancestor. John's father was Robert McGuffin baptised in Donaghmore near Dungannon in 1783, parents John and Margaret McGoffin.
Robert and Margaret Cooke were married in Drumglass, Tyrone on July 08, 1878 and had three sons that I'm aware of (likely more)...James, Thomas and Samuel.
I don't have birth or death dates for Robert if you could help me out. Margaret McGuffin (Cooke) died June 01, 1941 in Coalisland, Dungannon, Tyrone, Ireland.
