Which British socialite became 'Lady Glen Affric' in waiting, when she married in May, 2017?

Members of the Middleton family have been related to the British royal family by marriage since the wedding of Catherine Middleton and Prince William in April 2011, when she became the Duchess of Cambridge.

The Middletons' second daughter, Philippa "Pippa", born on 6 September 1983, attended the same schools as her siblings and studied English literature at the University of Edinburgh. There she shared a house with Lord Ted Innes-Ker, a son of the Duke of Roxburghe, and George Percy. Following graduation in 2008 she took an events management/marketing job with Table Talk, a London-based events catering company. She has written for 'The Spectator', 'Waitrose Magazine', the 'Daily Telegraph', 'Vanity Fair' and 'The Party Times', an online magazine which is an offshoot of her parents' company.

In July 2016, she became engaged to hedge fund manager and former racing driver James Matthews, eldest son of David Matthews, the Laird of Glen Affric. When he inherits his father's lairdship, Pippa will be accorded the courtesy title, Lady Glenaffric.

Pippa Middleton and James Matthews were married on 20 May 2017, at St Mark's Church, at Englefield Estate, Berkshire, near Bucklebury Manor, the Middleton family home. In June 2018, Pippa announced she was pregnant with her first child.
