Do you have dates or location? My Garrity family was in Kingston, Ontario, Canada. But left there after 1871. I don't know where they ended up.
RE:GARRETY/ GARRETTY/ GERRAGHTY/ GARRITY
Catherine McQuaid and John Garrity. Catherine is the sibling of John McQuaid is not found in the Ontario 1871 Census records. I suspect they headed for the US with thier family. That thengives a reason why they are not buried in St. Mary's RC Cemetery with the other McQuaid family members in Kingston.
