I've come across a very badly mashed-up outline tree which is supposed to cover the descendants of John Roy Grant, b. abt. 1706 in Craskie. The oldest son is listed as Alexander Grant b. abt. 1727 and the next son is Donald Grant, b. abt 1740. Notes on this Donald make it clear that he is the Donald Grant, Sr. of Craskie who settled on the lands of Sir William Johnson in NY, served in KRRNY and then came to Williamstown with Donald, Jr.
I have been trying to trace back the designation "Roy" or "Ruadh" which seems to have been given to eldest sons in my husband's Grant line. Since the earliest ancestor I can identify is Alexander, b. abt. 1733, I can't help wondering if our Alexander was this Donald of Craskie's older brother. So the question is: does anyone have information about the parents of Donald Grant, Sr. of Craskie?
