James Christopher Murphy

I am trying to make contact with my father, James Christopher Murphy who left when I was three years old in 1968. It is thought that he went to England. My mother did try to find him but never succeeded and she died in 1988. It would mean so much to me and my sister to make contact if even just to find out our medical history for the sake of our children who are his grandchildren. James is originally from Whitechurch Co Cork and lived there and also in Kells Co Meath and in Redruth Cornwall for a time. He worked in hotels and would be about age 69/70 now.He also has a sister (Mary Murphy ,I think but I don't know her married name) who lives in England.
