Research

Hi all... I am trying to trace my roots back to Sligo and any family that I may still have there. Unfortunately, I do not know much. My grandfather was Peter J. Hargadon born in Sligo, Ireland June 29, 1891 and died December 4, 1958 in Boston, MA. I believe his siblings were John, Delia, Theresa, and Nellie...any help would be great
