{Research performed by Diane Baptie, Member of ASGRA, 2002} A retour was filed in Lanark on 22 October, 1642 by Thomas Muirhead, heir of Mr. Thomas Muirhead, minister at Cambusnethan, his grandfather... There are few records showing the descendants of Thomas Muirhead, the minister, therefore this Thomas (the minister’s grandson) may have been a son of James Muirhead instead of William. It was assumed that if William was the heir of Thomas, then this individual would no doubt fall in the same line. (Lanark Retours #208.)
