This link will give you some info about the Towle or Wayne, SDhttp://www.smith-zimmermann.dsu.edu/smithz_cem_towles.htm
Wayne is the township in the NW corner of Lake CO. Towle is explained in the link. This cemetery is only a couple of miles from Oldham, SD which is in Kingsbury CO.
Adelia Towle came from English background. Could there have been a connection with the Chamberlins?
