Have you tried looking at The Ellis Islands records.
About 6 years ago I tried finding my Danish Grandfather'a Immigration record. I happen to come across a guy that was giving information to help some. Anyway he told my to try different spellings or or ways the the name could be spelled. So I tried that and sure enough there was my grandfathers records. His name is Hans Christian Bentsen but when I found it, its was spelled Hans Christen Bentzen. I asked the guy why it was spelled different, he said that back then they sometimes would spell the way it sounded and also sometimes if they trade ships it got miss spelled accidentally. When they arrived at Ellis Island they just had to over look it or they sent them back home.
