Lady Tatiana Mountbatten, the second cousin of King Charles III, has welcomed her second child.
The 34-year-old equestrian and psychotherapist, who is the daughter of George Mountbatten, Marquess of Milford Haven, and Sarah Walker, took to Instagram to reveal she’s had a baby boy – and shared his unique and meaningful name.
She posted a series of sweet photographs, including one of the newborn wrapped up in a knitted jumper, a cloud-print beanie and tiny mittens, under a cosy blanket.
She also revealed that she’d called her newborn Auberon, or Albie for short.
Tatiana also shared several photographs of her eldest child Elodie, who she and husband Alexander ‘Alick’ Dru welcomed in September 2023, and her family enjoying the start of spring in the countryside.
The final photo in her set was of her holding both Elodie and Albie close as they cuddled on a sofa, Tatiana smiling at the camera and appearing radiant.
In another picture, she simply showed his tiny hand holding one of her fingers.
She wrote in the caption: ‘March might just have been the best month of my life.

Lady Tatiana Mountbatten’s family has grown after the arrival of her second child, Auberon, whose big sister Elodie is ‘slowly getting used to him’
‘We’ve been in the country for a month, Auberon (Albie) has been really wonderful to look after.
‘His big sister has adored being outside all day every day and is slowly getting used to him.
‘We’ve played, rested, nourished, slept a little, loved a lot and enjoyed every minute of the glorious spring weather.’
However, the time had come for the family to head back to London, Tatiana said.
‘Now it’s time to head back to London, to return to normal – or discover what our new normal looks like, and slowly find our stride again.
‘Unbelievably grateful.’
Friends and family congratulated the family on their newest arrival, including Ella Mountbatten, daughter of Lord Ivar Mountbatten.
In a comment on the post, she wished Tatiana ahead of her birthday on April 16 and wrote: ‘My new little cuz Albie, he’s the sweetest Tats, congratulations and happy birthday for Wednesday.’

Tatiana also appeared eager to show Albie the reins of her beloved horses and to get him a pony of his own in the near future.
In reply to a fellow equestrian who asked when the royal would be buying him his first pony, Tatiana replied with an enthusiastic ‘soon!’.
Another commenter wondered about the origins of Albie’s name. Tatiana clarified that Auberon is Alick’s family name, as his father is Auberon Alexander Bernard Dru.
In October, Tatiana revealed she was expecting her second child in a post showing off her growing bump at the time in a form-fitting jersey jumpsuit by Max Mara.
At the time, she shared a photograph of herself proudly cradling her pregnant belly while at an event hosted by the Italian designer and wrote in the caption: ‘A private preview of my growing bump maxmara exquisite new collection.’
She and Alick had welcomed their first child Elodie in September 2023. She previously revealed that the couple did not know the gender of the baby and were keeping it a ‘surprise on the day’.
Tatiana and Alick married at Winchester Cathedral in July 2022. The bride wore an elegant gown by British designer Suzanne Neville that included a bespoke three metre train with embroidery from her mother’s wedding gown.
Tatiana is the second cousin once removed of King Charles, and the eldest child of George Mountbatten and his first wife Sarah Georgina Walker.
Her younger brother is Henry David Louis Mountbatten, Earl of Medina, while her stepbrother is Harry Wentworth-Stanley, the husband of Prince Harry’s ex-girlfriend, Cressida Bonas.
Alick, an entrepreneur who studied in Eton, is the son of Auberon Alexander Bernard Dru and Catherine Margaret Norden.
His father, known as Bernard, is the son of Major Alexander Dru and Gabriel Mary Hermione Herbert, and is a descendent of both John Vesey, 4th Viscount de Vesci, and Henry Howard Molyneux Herbert, 4th Earl of Carnarvon.
