Peter H. Thielen was born on 05 Apr 1862 in Racine, Wisconsin. His parents were German immigrants Heinrich "Henry" Thielen and Gertrude (Thelen) Thielen (my guess is that Peter's middle name was Henry). Peter was my great-great-grandfather.
Peter died of prostate cancer on 15 Oct 1935 at the State Hospital in Madison, Wisconsin, which is now known as the Mendota Mental Health Institute. I don't know how he ended up there, but the hospital records are at the State Historical Society, and I'm going to investigate whether it's possible to access them.
Peter was buried in Old Holy Cross Cemetery on Kinzie Avenue in Racine, in the Kurten family plot of his in-laws, beside his wife and infant grandson.
