In September 1963 Clan Munro Whisky – part of the Italian vermouth and sparkling wine specialist Martini & Rossi – bought the Lawson’s trademark, and agreed with the Distillers Company Ltd (DCL) to call the brand William Lawson’s, in order to avoid confusion with the DCL blend Peter Dawson.

In 1967 William Lawson Distillers Ltd acquired Macduff distillery in Banffshire, which had been constructed in 1962/63. Its single malt was marketed as Glen Deveron.
