Summary of what I am looking for in this thread:
Find out when the elder William Wenzel died (1881 in Wisconsin?), and where he is buried. Get an obit for him if one exists.
Confirm whether Charlotta and Edward were previously married before they married each other as described above. I need obits for them, which may help to prove that.
Otherwise, I made a ton of progress with this huge family and do not really need anything else!
