I have some possibilities. Tough cookie to crack. I'm a descendant as well. Anna and Jacob's daughter Bertha married Louis Arnoldini and died giving birth to my great grandfather Louis Arnold in 1917. I found something posted like an obituary (hand typed) that stated her brother was a Joseph Sadowski living in Herron Michigan. Her death was in July of 1940 and it seems she dies as a result of a stroke at riverview hospital. I didn't see any attached records though, so I questioned wether it was accurate. I have attached it. Also listed her as marrying Jacob in 1897 in price county. Their son Anthony is buried in Calvary chapel cemetary, Tomahawk, WI. This obituary did not list where she was buried. I cannot find a birth cert., death info or anything other than census information on both her and Jakob. This makes me question their names possibly changing. I found much more info on the Ungerer side. I have an original naturalization for Rudolph Ungerer (Jakob's brother) attached. If anyone wants more info, or has things to add PLEASE email me. I live about an hour from Tomahawk, so i might be able to do some digging "on foot". Deborahstencil@gmail.com
