I have the following I recorded from the marriage records of the Ontario Archives:
#9655-85 (Peterborough Co.): Patrick Galvin, 21, farmer, Ennismore, same, s/o John Galvin & Mary Gorman, married Mary Crowley, 20, Ennismore, same, d/o James Crowley & Joanna O'Keefe. Witn: Garret Galvin & Catherine Flood, both of Ennismore. 29 Sep 1885 at Ennismore (Rom Cath).
John Galvin was the son of Patrick Galvin and Margaret Cadigan (this comes from "Peter Robinson Settlers, 1823 - 1825," by Carol Bennett). Patrick was the son of Garrett Galvin and Mary Keene.
