Has the meaning of anyone else's name changed?

This question's a bit odd, I know, so let me explain: I first learned the meaning of my name (Braden) when I was 14 or 15 via a baby name book someone had brought to school (that would have been '94 or '95). My name was defined as meaning, "From the wide-open valley." In years that followed I would look at online databases and other name books, and the definition kept getting shorter, from "wide-open valley/spaces," to "wide-open," to finally just "wide" or "broad." This was the case until about 8 or 9 months ago when I looked again and now EVERYTHING says "Braden" means "Son of Bradan," and "Bradan" being a Gaelic word for salmon. I find this very odd, so I'm curious if anyone else has noticed if the definition of their name has changed in years past. Either that or if someone could explain to me why the meaning of my name has "changed," either one would be fine.

A baby name book I read as a child forty years ago said my name meant "elfin". Now all the books say it means "light". Wass up wid dat?

Reply:I know my own name has several definitions - it ranges from friend to something dealing with drunken builders???? Anyway - here is an odd longshot that may just assist you - this lady said it deals with 'sound symbolism' and astrology. It is kind of interesting and due to the letters in your name - I see where they are going with the definition trend.
