I believe we are looking for the same information. Your great , great, great uncles Charles (Karl) was born in Halberstadt, Germany and he had a brother names Fritz who's name changed to Fred later. Karl came to America in 1911 and Fritz 2 years later.
My grandmother was related to them, the two were her uncles. My fathers aunt used to receive packages from them here in America and she rembers them visiting her in the late 1930's, before the war with their whole family.
I can't find family member from Fritz, I don't believe he and his wife Louise ever had children and I believe he died in California.
I am looking for any information about Roland, but would appreciate anything that you may have.
Please contact me anytime.
