Leigh needs to be distinguished from Sir Francis Leigh I* and the latter’s son of the same name, who were members of an apparently unrelated Warwickshire family. This Member’s ancestors are first recorded living at Addington, on the border between Kent and Surrey, in the fourteenth century. They bought the manor in 1446, holding it in return for an obligation to prepare a dish at the coronation.
After studying at Oxford, Leigh was admitted to the Inner Temple in 1610, when pledges were made for him by two Surrey barristers, John Hawarde* and the future attorney-general Robert Heath*. Leigh’s uncle Sir John was an official of the royal Household, who rose to become clerk comptroller by the time of his death in 1624. Leigh also became a courtier, becoming a gentleman of the privy chamber early in the reign of Charles I.
In 1638 Leigh was committed to the Fleet for petitioning the king against a Chancery decree settling a disputed inheritance in which he had an interest as a result of his first marriage.
