Sorry to say that none of your surnames rang a bell; however, I am very limited as to my familiararity with names related to GAVAGAN. In Ireland, GGGrandfather Thomas married Elizabeth BEIRN (1812), but her name was changed to Burns here in the U.S. Their son, Robert (b.1830), my Irish immigrant ancestor, married Mary Agnes LYNCH in Boston in 1859, but from there I can only trace my GAVAGAN lines through their son, Thomas, my grandfather (b.1876), who moved from Boston to Providence, RI. Wish I could be more helpful, but I'd need some dates to give me a time line.
