Milly Alcock was born on April 11, 2000, to her parents, Emma Alcock and Mr. Alcock. She has never revealed who her dad is.

From an early age, Milly grew up with the support of her mother, Emma in Sydney, New South Wales, Australia. Emma's social media account publicly states her relationship status is divorced.

As we've stated her father is unknown, but a familiar name Ben Alcock mysteriously appears on her majority of Facebook post comments. And according to his profile, he is married to Grescha Brewer - a New South Wales-based salesperson.

Grescha is a mutual friend of Milly's mom, Emma. What we're talking about is just mere speculation, yet it could be - or not be so wrong.

Ben has also posted about Milly on his Facebook wall.

Milly stepped into the journey of acting through her small screen debut in 2014 - she was very young then. Alcock has not studied much; she has barely passed school and left studies to pursue her dream.

In an interview with Vogue, she states, "I knew that this opportunity would be so much more of a valuable experience than getting my piece of paper."

Meanwhile, the actress's family strongly motivates her to sustain her choice of chasing acting as a career. When Milly got the offer for the lead role, she said she was living in her mom's attic while washing dishes for a living before portraying the role in House of Dragons.

As the actress is blond-haired, she belongs to European Ancestry. Her heritage links back to the ancient Anglo-Saxon tribes of Britain. Talking about her nationality, Milly is Australian.

While growing up with her mom in NSW, Milly has done many things to expose herself to acting. Before joining acting classes, she used to do horse riding, and she loved to do skateboarding with her friends.

Milly often traveled to new places such as beaches and zoos with her mother, and she loved to post her activities on Facebook - and reply to the comments of her friends.

Alcock joined Sydney’s Newtown High School of the Performing Arts but left to seek a role in Upright. 

She played runaway teenager Meg, hitching across two thousand miles of the Australian outback, for which she became the champion of the Casting Guild of Australia Rising Star Award 2018. 

Even she got selected for Best Comedy Performer. Though, she lost out to her Upright co-star Tim.

Until 2022, Milly's workplace was in New South Wales, Australia; however, recently, she has shifted to London. For shooting purposes, Milly resides there - and she is seeking more opportunities in the Hollywood Industry.

Milly Alcock was raised with her brothers Bert and Eddy in her family. Both of them are currently living with their mother, Emma.

Eddy Alcock joined Stanmore Public School in 2010, but there is not much information regarding Bert's schooling.

Her brothers are into sports; once she opened her mouth in an interview, her family got mainly interested in Rugby Union and other sports with less interest in acting.

While remembering her childhood, Milly explains it would be totally incomplete without her brothers. Till now, both of her siblings are among the most influential people in her life after her mom.
