Hi!You might try to contact my brother @ email@example.com
He can put you in touch with people who might have information useful to you.
I am sitting here with my Dad (Hilbert JOhn Nebelsiek whose ancestor George Frederich Nebelsiek emigrated to the U.S. from Emerine Germany around 1888. George Frederich had 4 sons: Rudabert, William, Albert, Henry, and 2 daughters: Bertha and another one who died young) and my stepmom on the eve of his 80th birthday surfing the web; they've never been on it.So, of course, we typed in Nebelsiek.
Contact me if I can be of further help!!! Look forward to hearing from you.
