It's a new on me too, with such different spellings. On the other hand Tougher (I think it's that spelling) brings up Tower on IGI. It must have been the accent, perhaps a bit gutteral and indecipherable to delicate registrar ears--Only a guess though.
I also searched Ellis Island, I couldn't see anything for definate, but may have missed it. BUT they brought up many more spelling alternatives.
