When folks landed here (Ellis Island) their names were written down in large leger books. Sometimes they allowed the newcomer to write their name but many times the person keeping tallies had to figure out what the individual was saying and try to write the name as he or she heard it.
I know this thru reading back from long ago in my family history. The BEAM name has been written many ways. This (BEAM) is the American version. The original spelling from the land of what we now call Germany was BOEHM.
Whiskey it is.
