There must be a relationship. I have a John O'Hare and Margaret McConville.The names are so similar. Goodness knows they intermarried. I got the names from the death certif. of Bernard O'Hare b. 1883 d. 1928 Phila., PA, my husband's grandfather.I know he was from Ballintemple, Co. Armagh.He had a brother Peter b. 1886. John O'Hare's parents (or grandparents) I think were Cormick and Bridget O'Hare.Do you have them?
