Let me direct your attention to the DF13 Y-haplogroup tree. It shows the agnatic descendants of DF13, a Great King of Western Bell Beaker. [url]https://www.yfull.com/tree/R-DF13/[/url] Look specifically at Y32809.
Or don't bother. YFull has very little to say about it:
> R-Y32809ZS4588 * ZS4584 * ZS4582+13 SNPs formed 2100 ybp, TMRCA 550 ybp info
The "TMRCA 550 ybp" shows the most recent common ancestor of this clade to have been born 1450 AD (error bars = 1000 AD to 1750 AD). That's rather recent in genealogical terms, especially when we confirm that this man was Malcolm Drummond Chief of that Ilk, hereditary chamberlain of Lennox.
Refer now to [url]http://haplogroup-r.org/tree/R.html[/url] where this clade is called "ZS4584 ZS4586." This page shows THIRTEEN different men in this haplo-clade, divided into three subclades:
* two McRae
* three Sinclair/St.Clair, one Unknown
* six Drummond, one McRae
By consulting a 3rd source -- the public page of Sinclair Project Y-chromosome (group "12") -- we infer the Sinclairs are agnatic kin of Alexander Sinclair b. 1667? Glasgow, d. 1751 Virginia, an immigrant who lived to the age of 84. Unfortunately the Internet offers little opinion as to Alexander's parents. Do any famous Americans descend from him?
(I suppose Y32809 might be a smallish McRae cluster, with one bastard McRae who insists he's a Drummond sending in samples of all his uncles and brothers, packing the numbers. :-) But arguing against that idea is that R.Org is a huge database of Gaelic surname/SNP and [I]these six are the only Drummonds[/I] presented on the entire tree. 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.)
If we accept YFull's 1450 AD date, we can be blunt: Which Drummond cuckolded Alexander Sinclair's "ancestor"? Since Drummond appears monophyletic, we might guess the cuckolding occurred before Drummond fanned out. Be ready to rescind this as more Drummonds are tested.
If YFull's date is way off -- say that the Sinclair-Drummond split was 1150 AD or so -- we may guess it was Malcolm Beq's grandfather who played the two-headed game with Sinclair's wife or daughter. Note that Glasgow is almost adjacent to Lennox.
Note also from the subclade listing that a very early Drummond might have been sired by McRae. (This contrasts sharply with the old legend that Drummond came from Hungary. :-) )
