Drop the H?

I'm searching for a man named Harm Habbus for an upcoming issue of Casefile Clues. One suggestion in searching for him was to search for the last name of Abbus. An initial "H" is one of those letters that can get left off a name, depending upon how it is pronounced. Most sites that support Soundex searches do ignore the letter "h," but usually only if it is NOT the first letter. Could your "H" people be hiding without their "H?"
