The company was founded by James Paterson in Dumfries, Scotland, as J.A. Robertson & Sons, a hosiery maker of stockings and gloves. It exhibited hand-framed hosiery at the 1851 London Great Exhibition, opened a new Dumfries factory at the end of the 19th century, and added fully-fashioned wool and cashmere outerwear. Royal patronage followed: jacquard stockings reached George V and Queen Mary, and in 1927 the Prince of Wales was photographed on the golf course in a Drumohr sweater and socks.
Facing overseas competition and several changes of ownership, the Dumfries factory closed in 2003. In 2006 the brand was bought by the Italian Ciocca Group, and clothing has been produced in Italy under the Drumohr name ever since.
