I re-read your original message and realized I had some more information. RE: Johanna & John Talbot-->Johanna V. Cadigan born Sep 1875, Boston MA was a sister of Coneilus/Neil Cadigan. She married John Kerrin Talbot born 19 Jul 1875 MA. John's parents were John Talbot and Mary O'Neil. Does the gravestone mention when and where they died?
