THE DUCHESS of Sussex’s ex-husband has given his new born child a royal name.

Trevor Engelson, who was married to Meghan Markle for two years, recently welcomed his second child his wife Tracey Kurland and announced they had chosen to name it Sienna Lee Engelson.

Earlier this year, Princess Beatrice and Edoardo Mapelli Mozzi also named their child Sienna.

The child, the Queen's 12th great-grandchild, was born at Chelsea and Westminster Hospital on September 18.

Trevor announced the birth of his child on his private Instagram account.

“World, meet baby girl Sienna Lee Engelson… my wife is a gangster,” he said.

"I don't know what I did right, but I'm the luckiest guy I know."

Trevor began dating Meghan Markle in 2004.

The couple married in Jamaica in 2011, before separating after 18 months.

In August 2013, Trevor and Meghan were granted a no-fault divorce citing irreconcilable differences.

Trevor, an American film producer, went on to marry Tracey in 2018. The couple had their first child Ford Grace in August 2020.

The pair announced their engagement just two weeks Prince Harry and Meghan’s wedding in May 2018.

Trevor and Tracey went on to marry at the Rosewood Miramar Beach resort in Montecito, California, in May 2019.

Earlier this week, it was announced that the Mail On Sunday’s publisher will begin a Court of Appeal challenge in its ongoing legal battle with Meghan over a “personal and private” letter to her estranged father.

Meghan sued Associated Newspapers Limited (ANL) over a series of articles which reproduced parts of a “personal and private” letter to Mr Markle, 77, in August 2018.

She claimed the five articles, published in print and online in February 2019, misused her private information, infringed her copyright and breached the Data Protection Act.
