The second Viscount died an infant in 1689. The title was forfeited by the third Viscount in 1690, but continued to be used by the heirs-male, also Jacobites, into the next century.
The second Viscount's death as an infant led to a change in ownership of the title.  Despite this, the title continued to be used by male descendants of the family, particularly those who were supporters of the Jacobite cause, for the following century.
