The earl had five sons, one of whom became Henry Pierrepont, 1st Marquess of Dorchester, another was Francis Pierrepont (died 1659), a colonel in the parliamentary army and afterwards a member of the Long Parliament; and another was William Pierrepont (1608–1679), father-in-law of Gilbert Holles, 3rd Earl of Clare and also Henry Cavendish Duke of Newcastle upon Tyne. He also had a daughter, Lady Frances (born 1615) who married Philip Rolleston, Esquire. The earl was succeeded by his son, Henry.

In 1633 he bought Thoresby Park, where his son Henry built the first Thoresby Hall in 1670.
