Prince Harry, Meghan and Archie celebrate first Thanksgiving in their new home

Prince Harry, Meghan Markle and little Archie are celebrating their first Thanksgiving in their new Santa Barbara home.

It's sure to be a bittersweet holiday for the Duke and Duchess of Sussex, coming the day after they revealed the news of their miscarriage in July.

The family, who moved to Los Angeles in March just before coronavirus lockdowns began, will spend the day with Meghan's mum, Doria Ragland, according to People magazine.

"They are very happy," a source told the publication.

Adding: "Archie is thriving and growing quickly. As a family, they spend hours outside."

Meghan, who is known to be a big fan of the US holiday, will no doubt be cooking up a feast in the kitchen of her new Montecito home. Previously, the blogger shared photos as she cooked a turkey on her BBQ.

Last year, the family celebrated Archie's first Thanksgiving in Canada as they took a six-week break over the holidays to have some quality family time.

It was during this break they decided to step away from their roles as senior working members of the British Royal Family, announcing the move on their return to the UK in January.

The Duke and Duchess wrapped up their royal duties in March and first relocated to Canada briefly, before moving to Meghan's native California.

They've been busy appearing in virtual events and took part in Time100 TV broadcast.

The couple have also been seen volunteering for a number of charities in their new local community, including a drive-through Baby2Baby event just weeks after their pregnancy loss.

Meghan reflected on her heart-breaking experience earlier this year in an opinion piece for the New York Times, asking readers at Thanksgiving to show compassion and care for others in what's been a turbulent year for many.
