Seeking information on my ggrandfather, Dominic Dempsey, emigrated from Co. Sligo circa 1864 to USA and settled in Western PA. Married Bridger Con____? Had issue Michael, John, James, Thomas, Darby, Dominick, Patrick & Bridget. A Michael and Darby Dempsey also emigrated 1864 and lived on same street as Dominic, but their immigration papers state home as Co. Mayo.
Willing to explore any leads. Information will be sincerely appreciated.
