Hej Megan, I've look'd on-line and it says it's of Anglo-Saxon(English) origin. I've also notic'd that there is a "town" in Deutschland (Germany) that bares the name "Alden"! . This town is just northeast of Köln (Cologne). I'm not sure if there is a connection, but it, to me, looks that way. I also remember looking on-line once, and saw that the name Alden ment "Old Friend" or something close to it.
