Dylan

I can find no evidence that Dylan was used as a name for a real human being before 1910. The first example of Dylan for a real boy in the UK census is Dylan Mostyn Wathen, born 1910, lived with widowed innkeeper mother Hannah in Ystradgynlais in 1911. So Dylan Thomas was born only four years after the very first Dylan -- and it was his fame that later spread the name around the world.

Any way, any human fictional character named Dylan born before the 20th century is an anachronism. Before then it was only the name of the mythological figure.

This name can also sometimes be a Feminine name, making this name Unisex.

Dylan is also used as a feminine name. However, it's more common for males. So, I think that the "Gender" of this name should be updated from "Masculine" to "Masculine & Feminine". A known female bearer of this name is Dylan Lauren, owner of Dylan's Candy Bar in New York City.

This is a boy's name. I absolutely HATE hearing it used for a girl. People will always call you Mr. when they reply to your emails or online form submissions because it's a MASCULINE NAME. You might be denied service when you pick up your dry cleaning or a parcel at the PO because people might suspect fraud or suspicious activity. If you pay for anything on credit at a retail store then the salesclerk might think you've stolen a man's card because Dylan is a man's name for chrissake.

In 2018, 6 is the most common age for an American (U.S.) Dylan who is registered female with the Social Security Administration. It is the 2, 745th most common female first name for living U.S. citizens.

People say this is a unisex name, but if you look at the numbers Dylan is overwhelmingly male. At the end of 2015 there were 341, 741 males named Dylan in the United States (see The Social Security Administration website top 100 names of the last 100 years). As best I can tell there were 10,195 females named Dylan over the same period (see, ourbabynamer.com). So, Dylan is about 97% male and about 3% female in the US. Outside the US, the name is even more lopsidedly male.

My name is Dylan! I like my name and I like how it's fading in popularity! It's a very common, little white blonde boy name. And kinda preppy sounding... I don't like the name for a girl, probably cause I don't care for masculine sounding names for girls but anyways.. the name was very common in the early 2000s! Nicknames for my name are: D, D-Man, Dill Pickle, Dill, and Dill Dill.

I absolutely love this name. Me and my husband named our little girl Dilyn Nicole. I have noticed that everyone likes to have their opinion on what they think about her name. I have a feminine name and love it when people mistakenly call me Ashlee. I find my name boring. However, names are a personal preference and people should keep negative comments to themselves.

Number 24 for boys in 2005.

My name is Dylan, and I am a girl. The name 'Dylan' was originally a girl's name, as many people in Wales and Ireland and the rest of the UK know, and I am offended that you call it 'masculine' because I came here to prove to my friends that it was a girls name!
