Since this is a 10 year old message, you probably have the info already, but in case you're still searching:
The Jacob Henry Seelbach you mention is my great-great grandfather. He was born in Nassau, GERMANY, not the Bahamas. My great grandfather was Charles, and I have very little information on either of them.
My grandfather, Henry Jacob SeelbaUGH, Sr. (note the spelling change) passed in 1973, and my father, Jake Jr., still lives in the Youngstown, OH area.
If you have in the past 10 years found any info on Jacob Henry Seelbach, I'd be interested in learning it. If not, hopefully I've helped to give you a new lead.
