John Brennan

John Brennan and Mary Rice's marriage is listed in the records of St. Lazarian RC Church in Leighlinbridge, Co Carlow, for 24 Feb 1836. Mary lived in Seskin at that time.

(Note: if you are a descendent of John Brennan and Mary Rice and would like to compare DNA results, please let me know. I believe he was the brother of my 3rd great-grandfather Pat Brennan.)

They had 6 children that I know of:

1) Margaret, baptised 27 Apr 1837 at St. L's. She was with them in Beckwith, Lanark Co, Ontario in 1851, but that's the last I know of her.
