This has been going in for as long as I can remember. Look at my name, Leslie, and I’m a girl. Ashley has been used by girls for a really long time, and it was originally a name given to men. Girls use surnames also; Taylor and Kelly to name two.
Robin is used for girls and boys and I think is also a surname. I don’t know which gender used it first. I know a man names Kelly and a man named Tracy. Tracy is a surname also. I also know a man named Shannon.
I is think it’s true there has been a trend in the last 49 years to more and more give traditionally make names to girls. I read one article where a mom said she wanted her daughter’s resume when she looked for a job to be perceived as though she was a man.
I know two Jordans. One a man and one a woman.
Also, if you know people from many countries you see even more crossover. I’ve met more than one male Michele, and Rene/Renee both men and women.
I could name more examples of everything I talked about above.
