Hi, Cindy: I don't know if I can help you directly, but your Genglers (Jean/John) and his wife, Margretta, are listed in my great great grandfather's land deed. This would be the land directly across from the side or parking lot of St. Mary's Catholic Church in Lake Church, Town of Belgium, WI, i.e., the land fronts Highway D, right at the crossroads of Hwy D and Lake Church Road in the heart of Lake Church. The business built on that land is still open yet today.
John Gengler first bought the land on May 3, 1847. It was the West half of the South West Quarter of Section 13, Town 12, Range 22 east. This was recorded June 24, 1847 and was located in Vol. C. of Ozaukee County Deeds, page 144. Then, on June 2e, 1847, John probably turned a fast profit and sold the land to Peter Canoes (spelling of Peter's name changed later on to Knaus). This is in the same volume on page 145. I could send you a picture of the buildings that were put on this land. In 1893, my great great grandfather, Jacob SCHANEN bought the business on this land. It stayed in our family until almost 1964. There were many owners of this property after Genglers: John Longly, Paul Ronk, William Wiltgen, Nic Ronk, Peter Delles, J. Lauermann and Mike Bink, J. B. Krier, etc., before our family owned it.
Best wishes, Melissa
