On the Germany Pasenger Lists, www:genealogienetz.de is listed Friedrich Taddei 27 years old with his family (wife, sister? and child), from Hamburg to New York 19.03.1869.
I think I have got his birth record (3.03.1842 in Rosenberg, Prussia, now Susz, Poland). Parents: Friedrich Taddei & Carolina Gedies.
