In 1497 they aligned themselves as a sept of the Clan Munro in Ross-shire. The family had considerable tenure of lands around Tain. Their principal designation 'of Plaidis' was held until John MacCulloch, Provost of Tain, bought the lands of Kindeace from Munro of Culnald in 1612, after which they became 'of Kindeace'. The provost's descendant Roderick MacCulloch of Plaidis was an officer in the earl of Cromarty's Jacobite regiment in the 1745 rebellion. Incarcerated to the Tower of London, his life was reputedly saved after the intervention of a court noblewoman who had been struck by his courtesy and dignity as the prisoners were conveyed through the City. Other lands held by the Maccullochs in Easter Ross included Piltoun, Mulderg and Easter Drumm, the latter coming into their possession in 1649.
