At the time of its creation in 1620, the Grandison viscountcy was given special remainder to the male issue of his niece Barbara Villiers.

In 1626 the 1st Viscount Grandison was also created Baron Tregoz in the Peerage of England, with normal remainder to the heirs male of his body.

William Villiers, 2nd Viscount Grandison (1614–1643) was a supporter of King Charles I and died of wounds received at the Battle of Bristol in 1643.

Barbara Villiers, became the mistress of King Charles II and was created Duchess of Cleveland in 1670.
