They are in the Forest Hill Cemetery, Wyanet, Bureau County, Illinois. Walter died accidently, at a relatively young age in 1853, just a little over 43 years old. Susanna lived a long life, over 75 years, and died in 1881. Susanna is first, here, with a closeup and a full view.
Walter's is also shown in full view and in closeup.
Family is forever! ;-)
