I am the widow of David LEMKE of Muskegon, MI. There are several LEMKEs in the Muskegon CO and Ottawa CO area. I don't know if any are doing any research on the family or not. I now live in NC so I cannot help you very much. Here is what little I have:
1.Karl LEMKE b.16 Aug 1839 in Germany d. 31 Mar 1930 in Grand Haven, MI m. Willemina ELLMAN20 Feb 1870
2. Edward R. LEMKE (the first) b 3 Mar 1884 d. Dec 1970 m.Ida SHABEL
3. Edward Raymond LEMKE (second) b.19 Feb 1911 d. 8 Oct 1979 in Muskegon, MI m. Frances (Ferrol) BOLTZ
4. David Lee LEMKE b. 26 July 1937 Muskegon, MI d. 22 Feb 2002 Minneapolis, MN m. 29 Nov 1985 York, SC
I wish I had more for you. Theere almost has to be a connection there somewhere because I ubderstood that all the LEMKEs came over at about the same time and settled in either MI or WI.
