I am granddaughter of Hedwig Stanzel & Hjalmar Mathison.
Leopoldine Wanke Stanzel is my great-grandmother.
Last time I was at Plenty Cemetery there was no stone on Edward & John Wanke's graves.
My mother & I have the Mathison's back to Hans Peter Mathison in Denmark.
We have been trying to research the Henry Crooks-Lena Wanke family of Wisconsin & Iowa without much success.
We would greatly appreciate your assistance with any of the above.
