I ran some stats on my database and found the most gender ambiguous name was Casey- almost half are boys and half are girls as you can see from the above graph. I’ve always wondered what it would be like to have a gender ambiguous name. I have met a couple of male Kellys in my life but I’m sure everyone assumes I’m a girl when they see my name. I once read in Time magazine that Taylor Swift’s parents named her Taylor because that way her gender would not be immediately known, like if someone received her resume, and assumptions and biases could not be made (of course, with social media, if your name is at least somewhat unique, you’ll be found). In 1989, the year Taylor was born, there were 4800 males named Taylor and 4000 females, so it was pretty even back then. Since then girls have taken over the name- in 2013, it was 4000 females and 800 males.
Here’s a few other gender ambiguous names and which gender wins the count:
