An official defining characteristic of an earl still consisted of the receipt of the "third penny", one-third of the revenues of justice of a shire, that later became a fixed sum.
The eldest son of an Earl generally bears the courtesy title of Viscount or Lord; one refers to a younger son of an earl as the Honourable [Forename] [Surname] and to a daughter as Lady [Forename] [Surname] (Lady Diana Spencer furnishing a well-known example).
The 1st Earl's family and personal fortune was derived largely from mining on lands surrounding Lambton Castle, the ancestral family home in County Durham.
He was maternal grandson of the 4th Earl of Jersey and his wife, who was a mistress to the Prince of Wales, later George IV.
