Cody

I used to own a female papillon called Cody. I'd always thought of the name as male-only, and I didn't actually name her in the first place, as she belonged to our neighbours who were dreadfully irresponsible, and I ended up with her after they moved. I've worked with a few boys in childcare (at one Australian After School Care there were three Codys) with this name, never a girl, but it will always remind me of my little papillon sweetie.

This name can also SOMETIMES be FEMININE, making it UNISEX.
In the UK in 1996 and 1997, it was MORE common as a FEMININE name.

In 2018, 22 is the most common age for an American (U.S.) Cody who is registered female with the Social Security Administration. It is the 3, 203rd most common female first name for living U.S. citizens.

Cody is for a boy, Cady is for a girl. I think it's popular from Buffalo Bill, it's also a uniquely American name, even if does have Gaelic origins. Was very popular in the 1990s, so is always up for a revival.
