Lady Sarah Carnegie
Some of you will remember the start of Downton Abbey started with Lady Mary being unable to inherit because her previously arranged marriage to her cousin, the heir presumptive was in jeopardy because of his terribly inconvenient death on the Titanic. They then had to search for the rightful heir, who turned out to be someone they had never met. This has happened in real life.
In 2010 the 14th Earl of Northesk died from cancer and because he had no living sons his title was passed to a man he had never met! The 14th earl has three living daughters, Lady Sarah Carnegie, 30, Lady Fiona Carnegie, 26, and Lady Sophie Carnegie, 23, none of whom are eligible to inherit the title because they are the wrong sex. They have attempted to persuade the Crown Office to pass the title on down the female line instead, but have lost. So the title will go to the now 15th Earl of Northesk, Patrick Carnegy. Carnegy is a 72-year-old scholar of Wagner and Shakespeare. He was the eighth cousin, once removed, of the 14th Earl, whom he had never even met.
Ethie Castle
This all stems from Primogeniture, which is the law that the firstborn son inherits an estate. This allowed for estates to pass down from generation to generation intact. If there are no sons, the inheritance passes to the nearest male in order of descent. In order to ensure that if the Duke and Duchess of Cambridge’s could inherit the crown regardless of sex, they succession to the Crown Act 2013 was enacted. So if Prince George, was Princess Georgianna, she could have inherited the crown.
