My great great grandparents, Thomas Hanlon and Catherine McPhee, were married in Stratford, Perth, Ontario in about 1856. They subsequently immigrated to Iowa, USA about 1859. Thomas immigrated about 1853 from Ireland. I am trying to find the names of Catherine's parents. Her grave stone says she was born in Cape Breton, Nova Scotia on 31 Oct 1831. She must have moved to Ontario some time before she married. My information on Catherine leads me to believe that her Mother's maiden name was McDonald. Any leads would be appreciated.
