I am a descendant of David Fredenberg Sr. and David Fredenberg Jr. David Fredenberg Jr. was a brother of Herman, Ralph, and Louise to whom you refer to. Their father (David Sr.)and mother died shortly after the birth of the baby Louise. Many of the offspring of David Jr. moved to Milwaukee and lived their in the 1930 and their offspring continue to live in Milwaukee. Cook was the nickname of my grandfathers sister, and was one of eight children of David Fedenberg Jr. and his wife Amelia Barhke.
Herman Fredenberg married a Menominee. His son Herman Jr. although Menominee, lived in Window Rock, AZ as an employee of the BIA. I have much information on the descendants of David Fredenberg Jr., born in Wisconsin and who is buried in Shawano,WI
