Hi there! As I am originally from Michigan I can only say that I live in the City of Chicago and WOW is it a great place to live if you like Urban Environments. No, no other Kruger's here that I know of and your names sound unfamiliar BUT..........The KELM family was quite prolific in the 1800's and there are a whole line of Kelm's lost track of since Wilhelm Adolf KELM made the Ahnentafel in 1950. I am actually looking for some 3rd and 4th cousins, descendants of Matthias Kelm in Prussia. Any KELM requests that I get I'll never discount until I actually have proof of names dates and places. You never know who's going to be that link to the rest of your family. If the KELM's I am looking for are around; if they were anything like the other sides of the family, they too were terribly reproductive, and I probably have a huge extended family somewhere.
Let me know if you need any more help or if you want me to check mt KELM tree for given names!
