I knew a guy called Hillary, believe it or not Hilary was originally a man’s name, his mother added an extra “l” to his name to differentiate his name from the girl’s name which was then becoming popular, he hated the name but would at least point to the spelling difference to insist that his was a boy’s name.
You can well imagine his outrage when Hillary Clinton came along. Getting stopped at every passport checkpoint around the world as some official brightened up his day by guffawing “Heelarree Kleenton, ha, ha, ha, ha” got old very quickly.
Some occasional reasons to get a new name:
A friend of mine's original name was Stewart, which I like but he really did not like it and at the age of 15 he convinced his parents to allow him to legally change his name to Woody.
One time I was doing some political calling and the next person on my list was Mrs. _____ Butts. Mr. Butts answered the phone and I said, "Is this Mr. Butts?" Yes. "May I please speak to Mrs. Butts?"
Another friend of mine has the last name of Busam. Which is German and is pronounced "Bosom." He told me he once dated a gal named Candy. She was not marriage material on account of her name.
