I wanted to re-post some of my info. I've been told maybe from Cork.
My name is James Tobin. My dad was Vincent John Tobin, (born October 1920, Cambridge, Middlesex, MA) married Victoria Rose, my Grandfather was Richard Henry Tobin, (1893) married Francis Kermer. My Great-grandfather was William Henry Tobin, (1843) married a Mary Doran (Stapleton)
My G-G-Grandfather, Nicholas Tobin, married a Anne Temperance Wilson, and sadly, is the last Tobin entry I have.
Both my parents were born in Cambridge, MA, and most of my Tobin ancestors may have come from Ireland, settled in the New England States and/or Cape Breton, Nova Scotia
Thank You! James
