Aristocrat Lady Anna Gordon is set to become the first aristocrat to have a gay wedding.

Lady Anna, a descendant of Lord Aberdeen, is making history by being the first female member of the aristocracy to marry a woman.

She is engaged to her partner, 29-year-old Sarah McChesney.

The pair announced their engagement on social media. Alongside a picture of themselves, Lady Anna wrote: “What a weekend. Asked the love of my life to marry me and she said Yes – phew!”

They also formally announced the engagement by putting a notice in the Daily Telegraph.

The 28-year-old, works for Prince Charles as a business development manager at the Prince’s Trust Charity. She is the daughter of the 7th Marquess of Aberdeen and Temair.

The news comes after the Queen’s cousin, Lord Ivan Mountbatten, came out as gay earlier this year.

The 53-year-old came out in an interview with his boyfriend James Coyle, 54. The couple met on a skiing holiday in March, and the relationship has been a key landmark for them both.

He is the first member of the extended royal family to come out as gay, and whilst he is happier now he’s still finding his feet in his new relationship.

“I am a lot happier now, though I am still not 100% comfortable with being gay,” he told The Mail on Sunday.

“Being a Mountbatten was never the problem, it was the generation into which I was born. When I was growing up, it was known as ‘the love that dare not speak its name’, but what’s amazing now is how far we have all come in terms of acceptance.”

Coming out was the first big step for Mountbatten, who has no foreseeable plans to get hitched to his partner.

“Coming out is such a funny phrase but it’s what I suppose I did in a rather roundabout way, emerging to a place I’m happy to be. I have struggled with my sexuality and in some ways I still do; it has been a real journey to reach this point.”

“Simply talking about it in public is a huge step for me. Up to this point, I have had a heterosexual lifestyle, so living with a man is really new. One step at a time.”
