Kate Ferdinand has has welcomed her second child with her husband Rio Ferdinand, with the couple revealing their daughter's unique baby name.

The former reality TV star announced the happy news on Instagram, alongside a photo of the family's new addition.

"Shae Ferdinand," the caption read. "10.7.23. Our strong little girl."

Shae is the second child Kate and husband Rio share together, with the couple also having a two-year-old son, Cree, while Kate is also stepmother to Rio's three children Lorenz, 16, Tate, 14, and Tia, 12 – who he shared with wife Rebecca Ellison before she died of breast cancer in 2015, aged 34.

The moniker reveal certainly seemed to go down well on social media with many commenting how much they liked the choice.

"What a lovely name," one fan wrote.

"Beautiful name for this lil one," another added.

A few also commented that they had opted for similar versions of the name. "My daughter is called Shea but as I’m Irish we spell it differently but it’s traditionally a boys name but I love it for a girl so didn’t care," one user wrote.

According to Babynames.co.uk, Shae is a variant of the name Shea, which is Irish in origin and means "full of majesty".

"It can be given to baby girls or boys, but is more usually a girl’s name," the website reads. "There are lots of variations in the spelling of this name; Shae is quite an anglicised version and is often a shortened version of Seamus."

The Ferdinands aren't the only parents to think outside the baby box when it comes to naming their offspring.

Rihanna and A$AP Rocky reportedly chose an unusual pick for their son, naming him after Wu-Tang Clan leader naming him RZA Athelston Mayers.

And earlier this year Molly-Mae Hague and Tommy Fury shared the unique moniker they had picked for their newborn – Bambi.

How to choose a unique baby name

Sure you can take inspiration from the most popular lists. But, lead by celebrities, parents are increasingly looking to avoid being one of five Olivias on the pre-school register by opting for a moniker that stands out from the baby-naming crowd.

While research has revealed this is becoming more and more difficult, there are still some methods to uncover a moniker that's a little more unusual.

Check out the competition

Baby name expert SJ Strum, creator of the podcast Baby Name Envy, recommends visiting Names.darkergreen.com which shows a name’s popularity over the last 10 years.

“Some names are shown as zero ranked which means fewer than three babies were given that name in any year, which means you’re highly unlikely to meet another child with the same name in the playground,” she says.

Go transatlantic

Many naming trends start in the US, says Strum. “Check out Babynamewizard.com/voyager which captures the up-and-coming name trends – so you know which names to avoid before they cross to the UK.”

Make up your own name

Strum says popular ways to create your own name include blending syllables from the parents’ names or family members. “The trend took off in the UK when Katie Price and Peter Andre’s daughter Princess Tiaamii was named after Peter’s mum Thea and Katy’s mum Amy. However, it’s not a style which suits everyone,” she says.

Steer clear of popular culture

And avoid choosing a name from a favourite TV show, film or book. “No matter how obscure the character, others will have the same idea and instead of having a unique name, you may find your choice in the top 100 names for that year,” Strum warns. “Plus, these name choices also tend to date very fast.”

Go unpopular

Strum suggests choosing a name nearing the bottom of the popularity cycle. “Know many Beryls, Sues, Pauls or Brendas? Probably not,” she says. “If you want a name which stands out but is still well-known, this is a smart option – and it will come back into fashion eventually.”

Pick something personal

“The city where you first met your partner like Oxford or holidayed like Hudson for New York or a name associated with your favourite colour like Sage or Indigo is another option,” Strum says.

Moniker makeover

Try using letters from your favourite popular name to inspire other more unique choices. “One of my most popular baby name list on YouTube is 'daring alternatives to popular baby names',” Strum says. “So use sounds and letters to inspire you – for example James could become Amos. If you love Olivia; why not choose Verity?”

Opt for a theme

“Most people use A-Z baby name books or lists; but during a baby name search it’s important to spend most time finding the theme you love – it could be bohemian girl names, vintage boy names, or one syllable names to suit your last name,” Strum advises.

“Then you can discover more unique and daring names you may not have come across like Fable, Gilbert or short and sweet Seth.”

Research your family history

To unleash some old-fashioned gems. “One of Megan Markle’s ancestors was named Wisdom and doing some digging into your own family tree can see you branch out with a truly unique name which will also carry meaning for your family,” says Strum.
