Driscoll, Carey, Carberry

I am a descendant of Thomas Driscoll that came from County Clare. I know that he was born in the 1830's that he had a brother James and another brother or cousin Michael. There was also a John Driscoll and a Patrick Driscoll. His father was likely John Driscoll and the mother was Emma Connors.Thomas Driscoll went to Rutland Vermont and then to Montreal Quebec. He was married to Eliza Carey(sometimes spelt Cairey). I have been trying to find a record of his birth and marriage. I know the family history once in Montreal in the late 1850's but little before that time. Is there anyone out there that is related or has advice. The surname Carberry is also connected to my ancestor.

The parishes O'Callaghan Mills, Killuran and Clenlear appear in my research as well as the places Tulla, Killaloe, Kilkishen and Broadford in Couty Clare that my ancestors may have come from.
