McGuirks of the Parish of Bray

Searching for information on Thomas McGuirk and Catherine Col[e]man who were married in the Parish of Bray on 5 Feb 1827. They and their children emigrated to Canada around 1847. They died in Shefford County, Quebec, in 1881 (Thomas) and 1890 (Catherine). Several of their descendants went to the US and settled in Fitchburg and Worcester, Massachusetts. I am one of their many, many descendants.
