This is what I do know:
Paul Kerbs is (was-died in approx.1977) my grandfather. Brothers in Colo. include: John Kerbs,Tom Kerbs both of Yuma/Wray Colo. There are other brothers/sisters, although their names elude me right now....I am familiar with a Katherine (through memory) and possibly Reuben...... I will look further into it. I know there are others.
I would really like to know if they came from Germany or Russia... My grandmother (Lilly Goodman-Kerbs was VERY German....
