Proposed for peer review
Let’s follow the guidelines at the Geni project, Working with DNA, to evaluate the evidence.

DNA ties a descendent of John? McClure (B.C.) to a descendant of the Armstrong clan of County Fermanagh. It is therefore likely that John's parents married in the vicinity of Clogher, County Tyrone, and he was born there. We don't know the name of this Armstrong daughter but we do know she must have existed.
Karen Brauer commented:
there is a wide range of possible relationships for 15cM-25cM triangulating matches and that considerable evidence is required to document an 8th cousin inheritance path following each ancestral line. I do not find his conclusion viable as presented.
The "Working with DNA" guidance speaks only of confirming evidence-based relationships with DNA. Hypothesizing a common ancestor based solely upon a small segment of DNA is clearly outside the guidelines.
The proposal
John McClure b.c.1720 was in fact a descendant of John of Brookborough, via an unknown daughter who married a McClure.
Record evidence
The Clogher marriage records, while was a Church of Ireland diocese close to where John of Brookborough is thought to have lived, has several marriage records for McClures. Please page to the "McClure" section of this reference for details.
From this we know that a McClure family lived in proximity to where John of Brookborough lived, and we may even be describing some of John McClure's siblings.
Religion
The McClures were Protestants, as were the Armstrongs.
DNA evidence, as presented in the main profile for unknown daughter Armstrong
DNA ties a descendent of John? McClure (B.C.) to a descendant of the Armstrong clan of County Fermanagh. It is therefore likely that John's parents married in the vicinity of Clogher, County Tyrone, and he was born there.
We don't know the name of this Armstrong daughter but we do know she must have existed.
This private profile summarizes the evidence in detail. The gist of the argument involves two distinct chunks of DNA. The first chunk is shared among at least 7 individuals, of which 3 are provable descendants of John ‘of Brookeborough‘ Armstrong. Four are plausible descendants of the same individual.
In the first DNA overlap region, several individuals are proven descendants of John? McClure . I know only details of one of those individuals, due to privacy restrictions. But the obvious conclusion is that this McClure line is descended from the Brookeborough Armstrongs.
There is a second group of six individuals who are provably descended as well from this McClure line. This group includes two individuals from the first group, but the rest only overlap in the second section of DNA, and only one of these two is a provable Armstrong descendant. Thus, this second DNA overlap may or may not be Armstrong DNA.
