I suggest we conclude that the key father of this clade is surely Malcolm Beq Drummond of That Ilk himself, the Seneschal of Lennox born about 1200.)

Would it not be better to start with documentary research into his origins? Judging from some of what I've seen after a quick Google search, it's by no means certain that he was a Glaswegian or, indeed, even an immigrant (see some of the speculation at http://www.genealogy.com/ftm/s/t/o/John-E-Stockman/GENE19-0001.html).

To follow this up, there are more or less good abstracts of some relevant primary sources concerning this Alexander Sinclair at
It looks as if the first document definitely relating to this man is a deed of 18 March 1734 in which he is described as being of Stafford County, planter, and in which he purchased 377 acres in Prince William County (the above website citing PW Co. Deeds, Liber A, pp. 412-415). They also speculate - reasonably, given what I understand of population movement and boundary shifts in this part of Virginia - that he is the Alexander Sinclair named in a lawsuit in Richmond County from 1704.
What seems to me most interesting, though, is a citation to a manuscript land title book in the Virginia State Archives which apparently contains a deposition by this Alexander Sinclair dated 7 September 1745 in which he states that he is aged about seventy-nine years. This is, no doubt, the origin of the widely-repeated claim that he was born circa 1666. It's worth pointing out, though, that there's still nothing which definitively links this man with the indentured servant from Glasgow who went to Virginia in 1698, though I can see why interested researchers would have been quick to make the connection.
Again, I would want to see much more work done on this man's origins before it even began to be worthwhile speculating about a supposed connection with Drummonds.
All the best,
