Interesting thread I just stumbled on while doing a Google search for information on my father! I lived in MI until I went off to college, mostly in Mason.
While I don't recognize any of the names in the previous two threads, my father's family was from Jackson and I have names and some dates back into the 1800's, but little else.
My father was Leon J. Alger Jr (1931-1990), his father Leon J. Alger (1902-1990) and his father was John Cobb Alger, his father being John Alger. While I don't have dates for the last two, I figure that John Alger would have been born around 1840-1850.
