William's son became a Baronet of Nova Scotia by Charles I and this title is now extant. The Forbes Baronetcy, of Craigievar in the County of Aberdeen, was created in the Baronetage of Nova Scotia on 20 April 1630 for William Forbes. He was also a descendant of Hon. Patrick Forbes, third son of the second Lord Forbes, and the nephew of the first Baronet of the 1628 creation. The fourth Baronet represented Aberdeenshire in the House of Commons. The 5th Baronet married the Hon. Sarah Sempill, eldest daughter of Hugh Sempill, 12th Lord Sempill. Their grandson, the eighth Baronet, succeeded as seventeenth Lord Sempill in 1884 (see the Lord Sempill for earlier history of this title). The titles remained united until the death of his grandson, the 19th Lord and tenth Baronet, in 1965.
