I haven't changed my name legally, but the name I currently claim uses the same initials as my birth name, and the same surname, though for my personal protection I use a different surname online. I'm German, and my last name goes way back in Germany and France, so I can't give it up (plus it's one of the rarest names in the U.S.), so I guess I'm faithful to that like Marco is. My adopted first and middle names, Rafael Chacer, are a creation from the letters of my birth name, with the addition of an "F" because I liked the name Rafael so much. But the initials are the same. I always thought I'd choose something else, because there are numerous male names I love, but I've become pretty attached to my current name, and it's unusual, so I like it. Weird thing, though; I created it just randomly, like I said, with the letters of my birth name, and later found out the first and middle names (created) matched the etymology of my birth names. Strange.
