Thanks for all this, Kevin! I've also read your 'Version 6 Craskie Line' on ancestry.ca: it's all very interesting and compelling.
Sorry for my delay in responding -- needles to say, I do not check this site often.
I agree that we do not yet know who the parents of Donald Grant of Craskie (1744-1806) might have been.
The fact that an elder son was called Duncan may, as you say, be a hint, although there is evidence Donald Grant of Craskie ('the weaver') also had elder sons named John and Alexander, who may or may not have come to Canada, and whose years of birth are unconfirmed.
In the Loyalist claims, evidence is given in 1788 by a 'John McDonell of Baldrom' (which I take to be Ballintrom on your map, just east of Craskie) who says that his son and son-in-law went 'at first' -- i.e. joined Sir John Johnson's regiment in 1776.
These two are almost certainly John Ban McDonell (1743-1831), who settled on lot 9 in Glen Road (on the south side of the south branch of the River Raisin) in Chralottenburgh, and Donald Grant of Craskie (1744-1806) who as you know settled on lot 13 of South Branch Road in the same township.
One hypothesis is that Donald Grant of Craskie was married -- probably as a second wife -- to John Ban's sister.
Baptismal records from the Dutch Reformed Church at Fonda on the Mohawk show that Donald and Nancy (or Anna) Grant had a son Donald (born April 26th, 1778) and a daughter Mary (baptized October 28 1780, aged ten weeks) in Fonda, near their lands on the Kingsborough patent.
In this case, if Donald Grant of Craskie the weaver (1744-1806) had a wife named Margaret, as is often claimed in the literature, she probably died before 1778 -- a conclusion the oral record (documented but without written death records) seems to support.
A second hypothesis is that John McDonell of Baldrom's wife was a sister to Donald Grant of Craskie's parent, though this seems somewhat less likely.
My own reading of your analysis and that of John E. Grant and others (Goulet, Gressel, Young etc) is that there are currently two plausible options for the identity of Donald Grant of Craskie's father. He could be Alexander Grant (1710-43), younger of Craskie, the probable brother of Patrick (Black Peter) Grant (1715->61), or he could be a son of John Roy Grant (b 1705), who is often given as the brother of Isobel Grant (b 1702), who in 1720 married Patrick Grant VIII of Glenmoriston.
One issue that needs to be resolved is whether, as John E Grant and others have claimed, John Grant of Craskie (1663/71 - <1715) was also 'twice married' -- once in 1685 to Christian Grant (who was, controversially, his uncle's wife) with whom he may have had Patrick Grant (alive in 1737), 'elder of Craskie', and secondly around 1700 to Janet McDonell of the Cullachie family, with whom he has Isobel (born 1702) and John Roy (born 1705).
As for the distinction between John Grant of Craskie, who served in the Seven Years' War as a soldier in the 42nd regiment and subsequently received a Chelsea pension, and an Ensign Peter Grant, who was born somewhat later, I cannot comment because I have not seen the research carried out by our New Zealand colleague.
