I trust you, I was curious so I make a little research and after finding this athlete I continued to look and the results of my researches showed that this name is more used nowadays ( I've seen the percentage vary from 45/55%) in it's male form instead of the female form, of course take this info with a grain of salt, salso sorry if my post sounded rude it wasn't my intentions to belittle what you were saying.
Consider that as time change so the society uses and customs, just to give you an example here in Italy where I live we had a similar case with the name Andrea ( that's typically male), well a recent survey showed that in the last decade this name was used a lot for girls too ( like you I always I thought it was a common custom only in Anglo-Saxon countries where it is more common as a unisex name).
