Twelker - Germans to America

Hello to all!

Does anyone have access to the CD/book "Germans To America"?

I'm searching for any trace of Johann Christoph Twelker, born 22 Mar 1814 in oder near Bielefeld, Westfalen. He came top the US in 1846.
He is known to have lived in Franklin, Missouri; where he died 30 Apr 1907.

I would appreciate any information.

Thanks a lot in advance.
Merry X-Mas and a happy New Year to everyone!

Best regards,

Erik Twelker,
Bielefeld
