My great grandmother, Winnifred Tanney was born in St. Catherine's Ontaario around 1845. She married Richard Francis Nantelle and lived in Saginaw , Michigan. She died there in 1923.I am searching for information on the various spellings of this surname.Tanney/Tunney/Tenney....all spellings appeared in civil registers and "atlas" materials as well as census materials.Her mother was Brigid McGowan from Sligo , Ireland.Her father was Luke Tunney from Antrim, Ireland. I need a point of origin for these people.I think they came through Grosse Isle, Canada but am not sure.Please help with any information by emailing me. Thanks.
