Update from home records:
George Rickman 1836-1901 arrived from England in the US around 1894.
He had 4 Sons:
Alfred Walter Rickman (1862-19??), Arthur, Peter, William
Alfred Walter had only one son, my grand father, namely Charles Arthur Rickman 1891-1933.
I don't have any other info. This came from the Kalamazoo Historical Society. I know that the uncles went separate ways after my grandfather died in a construction accident in 1933. The Rickman construction business ended about that time. My Dad served in WW2 and never heard from his great uncles after the war. Vaguely remember someone could have gone to California, but that's it.
