Designed in 1956 by Jamie Scarlett MBE for Lord Kilmarnock and recorded in the Lord Lyon Court Books (LCB 3) on 7th March 1956. The Lords Kilmarnock are descended from both the Hays (the Earls of Errol), and the Stewarts and the design incorporates elements from the Hay-Leith tartan (the red section) and the Hunting Stewart (the green section) with minor alterations to each. The Boyd family are closely associated with the town of Kilmarnock in the South West of the Scottish Lowlands.
