O'Conor (Toomona)

The branch of the O'Conor family known as O'Conor Roe had extensive lands in county Roscommon which were confiscated in the 17th century and granted to Captain Nicholas Mahon, founder of the Strokestown family. Peter O'Conor was a descendent of the O'Conor Roe. He was the son of John O'Conor and his wife a Miss Dowell of Gort, near Athlone. John O'Conor was a grandson of Roger O'Conor of Castleruby, who was buried in the Abbey of Tulsk. Peter O'Conor's sister Bridget was the wife of Jeffrey Martin French of Rocksavage, county Roscommon. Peter appears to have died in the 1830s without any male heirs and Toomona was inherited by his sister.
