Are They Really "Unisex" If They're Only Used On Girls?

When discussing unisex names online, I'm always surprised at how many people are shocked or sympathetic for their poor old Uncles Kelly or Courtney or Marion. It must have been so hard growing up with a girls' name! :p
I'm not going to get into how I feel about girl-names and "weakness", so bypassing that, do people not realize just how many of our established feminine names actually used to be commonplace on boys?

* for the purposes of brevity, "elsewhere" = "every English-speaking country apart from the U.S."
Still haven't decided if the U.S. is leading the trends, or is just crazy.
