My g-g-g-g-g-grandparents were Timothy O'Connor (b.1786) and Eliza Gregg (b.1788) who came to Canada on the Stakesby from Mallow, Cork. They had Eliza (b.1806, m.5 Feb 1826 to William Green), Jane (b.1808), William (b.1811), Mary (my g-g-g-g-grandmother), Edmund (b.1816), Ellen (b.1819) and Margaret (b.1822). Timothy was a blacksmith. Eliza Greggs parents were Edmond Gregg and Mary Sexton. Is this your family?
