They were seated at Culrain which is in the south of the county of Sutherland, but to the north of the main Munro clan lands in Kiltearn, Easter Ross.
[2][1] The estate of Culrain was apparently named after Coleraine in Ireland of which George Munro, 1st of Newmore had been the governor.
[1] The Newmore estate had passed to the elder half-brother of George Munro, 1st of Culrain.
[1] The estate of Culrain later passed through several descendants until it was lost to Hector Munro, 8th laird of Novar.
[2] According to the 19th-century historian Alexander Mackenzie, the Munro of Culrain family was able to succeed to the Baronetcy of Foulis and chiefship of the Clan Munro as there was no male representative of the Munro of Culcairn family, who were senior in line to succeed but who were apparently extinct in the male line.
