My grandfather's name was Gregorz Grzybowski, and he came to MI from Poland with his wife, Maryanna; they had 6 children (the youngest, Sophie died at 18 mos of the flu epidemic of 1929). My grandfather also died as a young man from the flu epidemic. My father, as well as his brothers and sisters, have all passed way. I don't know where in Poland my grandparents came from, as I am just beginning to "dabble" in genealogy -- but I thought possibly this info may be of some use.
