The question I was responding to is: were all irish to Allumette from the same location in Erin.
For at least my ancestors experience they were not.
The Michael Cleary's came from County Clare and the (Irish) Thomas McGuires from Enniskillen in Fermanagh.(MaGuires bridge/castle). By census taker or by choice they dropped the Ma for Mc in Canada.
For basis, email me. email@example.com
Ancestry sells family info.
The Irish do not.
