You will be interested to know that a Gericke ended up owning the land in
Post twp. Allamakee Co. that my ancestor Elisha Harris purchased back in

newspaper that I've been busy transcribing:
...or on my personal web-site, which has lots of Allamakee Co. data-bases,
including plat maps (with more to come):
...and finally, if you haven't been there yet, check out the Allamakee Co.
Good luck to you,
In Alaska, but "My Roots are in Allamakee!!"
