Hi Richard, I was trying to find the history of a road in Door County, WI called Tryolean Pass. I just did a quick search to find that there were (last name) Netzer people in this area at one time. If your people came from the Tryol area perhaps they stayed in Door County for a time as they traveled into other parts of the state? People did come from Canada into Door County quite a bit. Maybe that's a clue for you or others trying to find the Netzer family in Wisconsin. :) Happy hunting! Oh, if you type in 'Tryolean Pass, Egg Harbor, WI' you will find it on the google map.
