Diana Miller, 9th Baroness Fauconberg
Diana Mary Miller, 11th Countess of Mértola, 15th Baroness Conyers, 9th Baroness Fauconberg was the eldest daughter of Sackville Pelham, 5th Earl of Yarborough.
On the death of her father in 1948, she inherited the Portuguese countship of Mértola, while she and her sister, Lady Wendy Lycett became co-heirs to the baronies of Fauconberg and Conyers, which went into abeyance. The death of her sister in 2012 terminated the abeyance in favour of the Countess, who succeeded in the baronies at that point. Since her own death in 2013, the titles are in abeyance once more.
On 15 November 1952, Lady Diana married Robert Miller and they had two daughters - co-heiresses to the baronies:
- Marcia Anne - adopted name: Anthea Theresa Lycett
- Beatrix Diana.
