My maternal grandfather, Joel William Irwin,born Nov 10, 1902, was the son of Thomas Jefferson Irwin, born in 1919, and Ida Mae Wolf. Thomas' father and mother were Joel Irwin and Emily Snow? They were married on Dec 24, 1901. I am seeking more information on these ancestors and their ancestors. The state of Wisconsin is mentioned, and Indiana. I need dates, names, places. My grandfather swore he was Irish and he mentioned there may have been native American, possibly Sioux, on his side of the family.
