Sharon, my grandfather was Joseph Slavinski-born about 1884 in Trenton, NJ. He married my grandmother (Mae/Mary Marron). They lived in Camden and eventually Atlantic City and Absecon. They separated when I was very young and Nanny continued to live with us in Absecon. (my mother Elizabeth Wilhelm was their only child).
From census of June, 1900, they show the greatgrandfather as Patrick, wife Hester and six children, mostly grown, working as potters (as my grandfather did, among other things).The boys were William, Henry,Joseph, Thomas and James--born between 1877 and 1882. Father was listed as a laboror. Both parents were immigrants from Ireland.
I see you are in NJ, and wondered if your greatgrandfather could be a brother? Any info would be helpful. I would guess Ireland would be a difficult place to get record--unless through the Catholic Church? Thanks,Joan Slavinski
