Diana Miller, Countess of Mértola


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:
When pregnant with Marcia, Lady Diana put her baby for adoption, which was agreed and accepted by Moira Lycett and her husband Michael, who changed her name to Anthea. In August 1958 Moira and Anthea were flying to London in a Central African Airways Viscount, which crashed near Benghazi. Moira was killed and Anthea injured. Lady Diana's family sought to reclaim the child to the exclusion of the adopted father who refused; in 1959, he instead fell in love with and married Lady Wendy. Anthea is among the Stuarts' Protestant ruling junior line and is a tenth cousin, once removed to Queen Elizabeth II; both descend from Elizabeth Stuart, Queen of Bohemia. Beatrix Diana married in 1991 Simon Armstrong, son of C. W. Armstrong who have two sons.
