I would appreciate any contact from researchers interested in the Kohn or Lersch/Loarsch/Lerscher/Loarscher/Locrescher family. You may also contact me directly at tgkohn_at_aol_dot_com.

I have very little certain information: a marriage record for Theresa Kohn and Michael Kohn and a naturalization record for Michael Kohn, 1872. I have also found a possible matching record of the 1800 U.S. Census in Kansas.

Michael had a brother living in La Crosse WI from 1855-1888. That family still has descendants residing there. Michael also had a brother living in Mitchell county KS from bef 1874-1919. That family still has descendants residing there.
