I located a record of a Franz Lang that arrived in Baltimore, MD on Oct 14
1833. He was nine at the time. Seems like this could be your man! It
stated the port of departure as Bremen aboard the ship Neptune. Lists the
ship type as "Brig" and states that Franz Lang was born in Shtenkdart. I
couldn't find the complete ship manifest this morning but I'll try to help
you further later today when I have more time. If you know anything about
the surname DeHarde, I'd love to hear from you. 
Our lines aren't related
at all....just thought I'd try and lend a hand.

Thanks Linda! I will check that out.
I don't have any DeHarde info...but I will keep you in mind if I come across the name.
Thanks again:)
