I am trying to find records on the Gilwee family (John and Margaret (Mullin)Gilwee) who came to Quebec from Ireland around 1830. The name has several variations from Gilwce, Gilwer, Kilwee and Gilwie due to transcription difficulties as well as likely name spelling changes. They are said to come from Sligo, Ireland, but I find no Gilwees at all in Ireland, so I am convinced the name was different before their arrival. I am not sure where the Sligo reference came from and it is possible they originated in some other area of Ireland. Also, I have found Margaret in some of the census records, but not John. He is listed in two of the children's baptism church records (the only ones I have found) Where was he at census? What was their original name? Why did they come to Quebec when they did?
Any information would be greatly appreciated.
