Marjorie Jessica Sutherland Thomson was a Scottish film, television and theatre actress. She is best known as a cast regular in the hit TV series Take the High Road from 1980 to 1995. In the programme, she played local matriarch Grace Lachlan, one of several "strong women characters (who) provided a focus". Series creator Don Houghton praised Thomson and her co-star Eileen McCallum for their clarity as speakers of the Scots dialect, an essential attribute of their respective roles in the programme.
