I don't have specific knowledge.
I know that Joseph, Barbara and children Veronica, Frank, John and Valentine Jesch came from Bremen (& via Southampton) on the ship "New York", arriving in New York City on 29-Aug-1864.
The book "Hrenchir Family & Other Moravians of Brown Co, KS" by Joan Hrenchir may have some additional information if you can locate a copy of it. I had a copy, but seem to have misplaced it (probably loaned it out to someone).
