I have a Marguerite Meehan, born around 1830 to John Meehan and Ellen Sullivan who came over to Halifax (today it's St. Ferndinand d' Halifax, Quebec, Canada. She married a Michael Mimnaugh 1/30/1866 and was left a widow and married Thomas Watts on 12/6/1881. I'm not sure where this family came from in Ireland. She had three brothers, maybe four.
Thomas born in l829; Thomas born in l823; William born in 1836 and possibly a brother named Charles. Problem: there was two John Meehan's living in Halifax at the same time.
