Designed by the 1st Earl in 1813, the Hogg-Marchmont coat of arms consists of four basic elements – the shield, the supporters, the crest, and the motto. The shield is winged and divided into four quarters in which there are pictures of a goblet, a knife, fork and spoon, a piece of stilton and a jar of pickled eggs. To the left and right of the shield are two rampant sows. On top, rests a golden Earl’s coronet.
The family motto is written in Latin underneath on an unfurling banner. It reads “Unum In Via”. The 6th Earl insists on translating this as “Have One For The Road,” but the actual translation is simply “One Way”.
