Hi Anne, thanks for your note! I will answer some of your questions here in case anyone else can also help or use the info, and I will also send you an email.
The evidence I have that Bridget was born in Castlemartyr is the grave marker in Ontario. I have tried to attach the photo here but if it doesn't work I can send it to you. It says that she was born in 1820 at Castlemartyr, Cork, Ireland. It also says Thomas was born in 1803 at Mount Uniacke, Cork, Ireland.
On the side of the marker, it notes the 3 sons that died at sea in 1856: Dennis (age 13), John (age 11) and Thomas (age 9). These boys and another Foley, Daniel, whose relationship I don't know yet, died on the ship Pallas when it hit the rocks of St. Paul Island near Cape Breton Island. There is an article in the Cork Examiner 2 July 1856 about this wreck.
It appears that Thomas' son Michael did come to Canada. In the 1861 Census of Canada West (now Ontario), there are 2 Foley families living side by side. The first is the family of a Michael who appears to be Thomas' big brother. He a widower age 57. His children are Andrew age 27 (born in Ireland), John age 25 (born in Ireland), Thomas age 23 (born in Ireland), Catherine age 21 (born in Ireland) and Mary Ann age 13 (born in Canada West).
In the house next door is Thomas' family, with Thomas listed as age 55, and Bridget age 40. Their children are Michael age 21 (born in Ireland), Margaret age 19 (born in Ireland), Honora age 10 (born in Ireland), William age 6 (born in CW), Mary Ann age 4 (born in CW), Dennis age 2 (born in CW) and Henry age 1 (born in CW).
It appears they farmed together on 70 acres of land.
One thing that I cannot figure out is when the family came to Canada and how. The 3 boys were the only children in their family on the ship in 1856, possibly travelling with an Uncle Daniel. But no other Foleys were aboard. Honora was the last child born in Ireland, in 1852. William was the first child born in Canada, in 1855. I wonder why the youngest children would be travelling after the rest of the family? Or maybe they came in small groups, as they could afford it?
I'll be very pleased with any information you can give me!
