Can you answer this question (?) Who, what, where is the oldest McGregor Clan [member] Last Will & Testament in existence. I am seeking this information. The oldest that I have found so far is 1550, January 14th, -- Gilbert Grierson. Can anyone help me with this vital question? There is a Robert Greig or Grig, dated January 24th, 1565 - Troylus Greigsoun dated December 24th, 1576 - an Agnes Grigsoun dated June 23rd, 1587 - a John Greig or Grig dated January 26th, 1565 - a George Greig or Grig dated July 27th, 1565 - and the second oldest: Patrick McGregour, dated March 19th, 1552 - he was at Eglischenochtis, Parish of Kylmadock - Testament Testamentar in the Court of Dunblane Commissary Cout.
