These names were given to actual children and, according to the experts, might actually be on the rise.

Giving your baby a ‘unique’ name has become a competitive sport amongst some new parents, but these names take it to an all new level.

Pamela Redmond Satran, co-founder of online name bible Nameberry, has weighed in on some of the more peculiar names that have been given to babies.

Here’s what she had to say about the craziest picks of the bunch.

Billion

“Cash is an up-and-coming baby name, and Rich has been around for decades.  So how about coming out and naming a number?  Billion was used for five baby boys for the first time this year, though there were also 11 boys named Million and babies of both sexes named Amillion.  And down the road, maybe we’ll see Trillion or even Kazillion, neither of which have yet reached the five-baby threshold.  But at least with Billion, you can call him Bill or Billy.”

Royaltee

“The advent of the second royal baby may have inspired a lot of royal-related baby names, but we’re not sure that new choices such as Royaltee, Royalti, and Royel set quite the right blueblood tone.  They were joined by Kinganthony, Kingmichael, and Princecharles.”

Sadman

“This name makes us so sad, man.  As grating as the ‘uplifting’ new names like Excel (seven girls) or Legendary (five boys) can be, they’re an improvement on a downbeat name like Sadman, given to five boys last year.”

Wimberley

“On a lighter note, Wimberley is a particularly entertaining member of the kind of new name introduced by parents looking to improve on an original by giving it a new first initial, or switching a few letters or sounds around.  The trouble is, it usually doesn’t work.  Kimberley, if dated, is still so much more appealing than Wimberley. Jaylen is better than Xaylen, another new name, and Brooke more attractive than Rooke.”

Dagger

“Where will the trend for Bad Boy names end?  Dagger is one of the new violent names added to the lexicon this year, used for five boys, but we also welcomed five boys named Renegade, six boys named Kaliber and six named Bulut, along with seven girls named Rocket.  And those are just the new names: there are growing numbers of babies named Gunner, Wilder, Cannon, and Blaze.”

Londynne

“Place names for babies have taken off in recent years, with London in the Top 100 for girls and at Number 611 for boys.  But such popularity inevitably spawns spelling variations, with Londyn ranked at Number 154 for girls.  And now we travel even further with nine baby girls named Londynne. Also new to the lexicon were Sicilee, Millan, and (Lord help us) Jerzei.”

Redmond Satran also named Ruckus, Swastik, Common and Lay as interesting names on the rise when she spoke to Yahoo Parenting.

What do you think of these names? Would you use them?
