Another MacCulloch family, the MacCullochs of Plaidis, established themselves in Easter Ross in the Scottish Highlands by the 14th century. They were first noted as followers of the Earl of Ross and Clan Ross. The family however, are believed to have originated outside the north-east, and there are some unsubstantiated claims of an ancestral connection with the Galloway McCullochs. Certainly, Sir Hugh MacCulloch of Pilton (d. 1688), from the Easter Ross line claimed cousinage with the lairds of Myreton and matriculated arms that advertised the affinity.
