Am trying to discover if there is any relationship between the three Harty lines who came from Tipperary Co. near Nenagh in Ireland and emigrated to the London and Lucan areas of Middlesex Co. in Ontario. They are:

Unrelated family # 1: Michael O' Meara born about 1790 & married in Dunnkerrin Parish Co. Offaly to Mary Harty - Children who came to Canada include: Elizabeth born 1829; Michael 1832 and Roderick.

Unrelated family # 2: John O' Meara born abt 1755 - 1765 Tipperary Co. and Bridget Harty born abou 1770 - Children who came to Middlesex Co. Ontario include: Mary O'Meara Collisson; Catherine O'Meara Donohue; Margaret O'Meara Morkin; Timothy O'Meara. These family members emigrated between 1842 and 1858. Three others in this family remained in Ireland.

Unrelated family # 3: John Harty born about 1750 and Mary ? both born in Tipperary Co. - Children who came to Lucan Ontario include: William Harty b. about 1780 married Mary Rigney; Mary Ann Harty born 1793 married John V. Ryan; Patrick Harty who married Sara Feehely.

Does anybody have any information, clues or documents that might lead to a connection between these families? Kathleen Logan Harty / O'Meara / Donohue descendant.
