I do have a Thomas Finn who b. 1835 my gg grandfather. He arrived in NY April 1855. I am not sure of his parents or sibblings. He later married Catherine O'brien. She settled in PA for awhile before coming to MN. I know of a William Finn who settled in NY (mid 1800's) who is a relative but I can't seem to locate him on any census as of yet. Sorry don't seem like I'm very much helo to you at this time. Good luck!! Linda
