While all of us know a Jack, John or James, not everyone will have come across a Yseult, Xerves or a Youngblood.
But if you do then it means you're keeping prestigious company as, according to British society bible Tatler, these are the poshest baby names of all time.
The magazine has revealed the definitive list just in time for anyone who's having a New Year baby to make sure their youngster grows up with a touch of class.
"Last year we gave you the poshest baby names of 2017, now we bring you the definitive list of perennial Sloane favourites that have lasted generations,' said Tatler.
"You've been crossing your legs very hard, but you can finally give birth because Tatler has published its eagerly anticipated list of the most aristocratic baby names of all time."
There were some well-known names on the list like Amanda, Harriet and Imogen for girls and David, Henry and Oliver for baby boys.
But more unusual choices for girls included Quintana or Yseult, while upper class titles for boys include Unwin or Vere.
If you don't move in aristocratic circles, you're probably more at home with Oliver and Olivia which topped the charts of baby names last year - while Jaxon, Muhammad, Charlotte and Willow also surged in popularity.
Oliver was the most popular boy's name for the fourth year in a row - although if all variations of Muhammad are grouped together that is more common.
Amelia lost the top spot for girls born in England and Wales after holding the number one ranking for five years.
Charlotte moved up 13 places to number 12 - probably reflecting the Duke and Duchess of Cambridge's choice for their daughter in 2015.
Third in line to the throne, Prince George also saw his position reflected in his name's third-place ranking.
