I am looking for information about Patrick Shea and his wife Mary McMahon who immigrated to the province of Quebec about 1825 and according to their son's (James )marriage record in 1857 at Notre-Dame church in Montreal, both parents were deceased before 1857 and were from St-Columban parish. Unfortunately, there's no trace of Patrick Shea married to Mary McMahon in the St-Columban parish.
