Hi David..I know your inquiry was made a few years ago and I don't know if you are still looking for a response however I have some information that may be helpful. My mother's maiden name is Dower and she came from Miramichi N.B. Her father's name was John Dower aka Jack and he married Muriel McLean whose mother was Agnes Craig. My grandfather had 2 siblings. A sister named Mary who married Andrew Doyle and a brother Everette.
If this information is of help or if you want to discuss other possible connections, I'd love to hear back from you.
Thanks,
Karen
