I am searching the family of Anna barbara Pietsch and her Husband Anton herrgesell ancestors who may have stayed behind when Anton and Franziska and 4 girls came to USA via bremen in 1866.
Our village was Engelsberg in Austria/ Bohemia. They sailed on ship called Hansa.
In Engelsberg Anton had a flouring mill-stone mill till 1864.
Good luck on your search. I think our people came thru NY Castle garden port.
