One of Sampson Lennard's daughters, Margaret, married Sir Thomas Waller, at one time lieutenant of Dover Castle and the younger son of an important Kent family, with their seat at Groombridge. An unusual term in the marriage covenant stipulated that Margaret and Thomas should live at Knole which is where Margaret gave birth to her son William, probably in 1598. The baptism is recorded in the Sevenoaks parish register for 3 December. In 1613, William inherited his father's baronetcy, becoming Sir William Waller. He later commanded a parliamentary army with some distinction during the English Civil War.
