My maiden name wasn't four letters, but it was common. My married name I must spell out constantly. The worst part is, it is an English name, spelt just like it sounds. It's just not that common of a name. If it was Polish or Slavic or something I wouldn't mind so much.
My new one isn't English but it is pronounced just like it is spelled. However, I find people want to add letters to it or mispronounce the vowel sound in the middle. If they would even try to say it by just sounding it out then they would have it right the first time.
