[3] The clan is likely related to the English Forrester´s of Etherstone and later Forster´s of Bamburgh, sharing the same bugle-horned arms.
[3] According to historian Alexander Mackenzie, Gerse or Grace, sister of Sir John Forrester of Corstorphine, possibly married Robert de Munro, 8th Baron of Foulis.
[3] There was a Stirlingshire branch of the clan, the Forresters of Garden who were heritable keepers of the Torwood (a Royal forest and hunting ground).
[3] Sir Duncan Forrester, 1st of Torwood was Comptroller of the Royal Household for James IV of Scotland.
[3] In 1679 he was murdered by his mistress, Mrs Christian Nimmo and his brother who was mad then inherited the title.
[3] Eventually the male line died out and the title descended through an heiress to the Earls of Verulam.
[3] Two cadet branches of the chief's family in Normandy, France are Le Forestier du Buisson Sainte-Marguerite and Le Forestier de Foucrainville who descend from Sir Adam Forrester of the 14th century.
