I am looking for information on my great great grandmother Mary Foy who was born circa 1841. Census returns show she was born in Killeevan, Monaghan. Mary married Charles Rielley/Riley/Reilly from Cavan and moved to Scotland in the early 1860s. They moved around the UK, eventually settling in Stockton-on-Tees in the North East of England where they raised their family.
I have found a Patrick Foy(e) farming 8 acres at Drumreenagh in the Tithe Applotment Books in 1825, a Charles Foy who witnessed a marriage in Newbliss in 1863 and a family headed by Margaret Foy living in Drumreenagh in 1901 and 1911, but no indication whether these people are linked to my Mary Foy.
Any information or suggestions for how to continue my research would be most appreciated.
