Geoffrey Lachlan Fairbairn (F-39)

WebIntro(Matches)Descendant F-35 of the Kelso line of James & Margaret (LEARMONTH), and & (Eckford:F-27) of the engineer Robert (married Elizabeth YOUNG) are showing as an excellent match (66/67) in lineage 1 (Haplogroup I1).
For now they remain in the overall lineage 1a as the markers they share are faster mutating markers: 570 = 18 and cdyb=37.
The more recent addition to the matches is that for Geoffrey (F-39) who is a 67/67 match to Eckford:F-27.

F-35's line can plausibly be traced back to early Kelso as far as Francis and Agnes (DICKIESON) FAIRBAIRN, married there in 1704.
F-39's to Robert & Elizabeth (CROSBIE) FAIRBAIRN.
F-27's is more problematic.
The earliest ancestor for F-27 is a civil engineer Robert, born Eckford, with no matching baptism handy, it is rather hard to slot him into his rightful place on the tree. His age in the only confirmed census sighting (1851 Bothwell, LKS) is unclear and could be 42,52 or 62. Given the age of his family, 42 seems the most likely, which would make him born about 1809 - not that that helps find either his birth, or death.
He cannot be the Robert born to Robert and Elizabeth (CROSBIE) as he is fully accounted for.
It is tempting to say that he's the Robert son of Alexander and Isabella (ATCHISON) who married 1808 Coldstream, given that Robert also appears to have a son John born Coldstream, but that should make F-27 most closely match Robert(F-34) instead.
Robert(F-34) is in lineage 1, but one of those only GD1 from the modal for all of Lineage 1, rather than in this potential subgrouping (on faster markers only 570=18 & cdyb=37).

Dec 2017 saw two new lineages added to the SNP created for the initial four Lineage 1e BigY testers. Which means the preliminary yFULL MRCA estimate of formation abt 1725 has to be optimistic. The ELLIOTT tree is at the very least a contemporary of the progenitor of the Lineage 1e FAIRBAIRN BigY testers. This 1b4b line could technically still belong under Lineage 1e, even though we don't have a paper trail. 
WebSummaryFor the 111 marker matches:
The Time Predictor report (TiP), given no known connection within 4 generations, shows a probability of 90% for a shared ancestor within 8 generations to the closest match (one of the matching ELLIOTTs), 97% within 10, 99% within 12.
For the closest Fairbairn match, same no known connection within 4 generations, the probability of a shared ancestor within 8 generations is 75%.
Starting counting at 1 for the tester, 8 generations would be John (marr. Magdalen BO) born abt 1685.
For the nearest BigY tested Fairbairn (G Roy F-3), same criteria, probability within 8 generations is only 58%, within 10, 78%.
Will be interesting to see what BigY eventually does to split out into different sub branches.
