I am looking for my grandfather's grandparents. The information I have is that the family lived in Flint, there were two children: John P (my great-grandfather, born 1865) and a sister Kate. I know that the mother died in 1898, but do not know her name. The father's name might be Thomas. Kate married William Hafner (Haffner, Hefner) and had two children; this family was understood to still be in the Flint area as late as the 1950s. John P lists his father's birthplace as Ireland on all the census records. Not a whole lot to go on, I know.
