I should have emphasized that I have over 200 pages in my family tree for William McGrath. My road block is finding the connection in Ireland. This is true for all but one of the Irish families I am researching. In most cases I can get to the County and maybe the parents but no farther. Many were born circa 1750 to 1810 and settled in Cape Breton or Nova Scotia 1790 to 1830 but the majority were born circa 1800 and settled in Cape Breton 1818/19. There are four families of McGrath with 10,000 plus descendants in Canada, USA & Australia. My interrelated families are: Hearn, Doyle, Keating, Kehoe, Kavanagh, Kiely, Kenny, Power, Britten & Flynn.
