Hallo Mrs Moore,
I read your question because your Great-grandfather Weber. You think
right, Coburg is now an Part of bavaria since 1920. To 1918 ist was a
Duchy Saxe-Coburg and Gotha oder before Saxe-Coburg-Saalfeld from 1735
to 1806 and to 1826.
From the Coburg area I know ohnly one man with the Name WEBER, his first
name was Nicol, = the short form of Nicolaus oder Claus, he startet in
Coburg 25. April 1849 to USA, he was a journeyman mason.
I hope I can help you in moment.
Still one question: Know you the firstname of great-grandfather, or know
you where he ist born? Know you the name of the brother?
