Thanks for the reply!
I have Josephine's parents in my database, but as names only, no other info.
Two of the MI brothers went to the Bohemian village of Havilckov Brod, (where the density of Nachazels seem to be the greatest, according to an engineer in Prague whose name was Nachazel) and found several burial sights. On inquiry, found most records were destroyed in WW II, so they gave up.
I have not pursued the FHL offerings (except on-line), as I was told by another reasearcher there wasn't much there. But I will have to agree; better to see for youself. The FHL site you mentioned, I have been through, including copies of the images.
In "German Immigrants: ...............Bremen to New York, 1855-1862" Passenger list, we find; Johann, Mary, and 2 children: Mary Theresa, and Anne. So yes, there was children born in Bohemia!
