Wellington succession secured

Daily Mail today reports that the succession to the dukedom of Wellington (and a whole string of other titles, including Prince of Waterloo) was secured for a third generation when the Earl and Countess of Mornington became the parents of twins last week.
The girl has been named Mae Madeleine, while the boy, who will be styled Viscount Wellesley, received the name Arthur Darcy. Arthur is also among the names of his father the Earl of Mornington, his grandfather the Marquess of Douro and his great-grandfather, the 8th and current Duke of Wellington - and of course of their ancestor, the 1st Duke of Wellington, who defeated Napoléon I at Waterloo and later became Prime Minister of Britain.
The newborns also have many other illustrious ancestors. Their mother, née Jemma Kidd, is a great-granddaughter of Lord Beaverbrook, while their paternal grandmother, née Princess Antonia of Prussia, is a great-granddaughter of Emperor Wilhelm II of Germany. As he was a grandson of Queen Victoria of Britain, the twins also have very remote places on the list of succession to the British throne.
