WebIntro(Witness) With an excellent genetic match (66/67) between John(F-17), descendant of John and Jessie (JOHNSTON), and Stewart(F-38), descendant of James & Isabel (TAIT) it would seem likely that the suspected family group for John & Magdalen (BO) FAIRBAIRN shown on the Summary Patriarchs page may well be reality.
In addition Stewart(F-38) has exact matches (67/67) with Robert F(F-34), and (F-42), and (F-42) a highly probable paper trail match with a GD2 genetic match to RJ(Bob) F-44.

Stewart (F-38)'s line of James and Isobel (TAIT) is believed to track back to John and Magdalen (BO) of Lidgatehead, Fanns in Earlston in the early 1700s.
RF(Bob)F-34 represents the line of the Alexander and Isabella (AITCHISON), so far only traced back to James and Agnes (LINDSAY) with children born Ednam in the 1780s;
(F-42) represents the line of John and Helen (ATCHESON) who married in Edinburgh,and were rebuked for so doing in Legerwood in 1771, children born Smailholm, then Earlston, possibly Mellerstain.
No immediately obvious link presents itself between these three, but if Alexander is a family name for Bob's line, perhaps there's a link with one of the Alexanders contemporary with the John of Stewart's line.
The Alexander married to Betsy NEWTON however is spoken for, as is his son James (married Agnes BRACK 1783 at Lauder).
Exploration of a possible AITCHISON link may bear some fruit for a connection between F-42's and Bob's lines, and with Alexander being a family name (for F-34), possibly there is a connection to one of the early Alexanders in Mellerstain, Earlston?
      
GeneticDistance(Testee12Markers) At 12 markers the theoretical Genetic Distance (GD) calculations from John show: 1 to Doug(GOODFELLOW), David(TROTTER), Patrick, David(CAMPBELL), Joe, Mike(IRWIN) and Tom; 2 to Earl, Roy, William, Michael, Doug(BLAKEY) and Martin; ie belonging to "clump 2" of lineage 1, and being the only one in all of Lineage 1 to have marker 389-2 as 30. At 25 markers these GDs change only for those with different results for a marker signifying their line alone - (F-8), Doug (F-14) and William (F-12) all slip by one. 
GeneticDistance(Testee37Markers) At 37 markers the theoretical Genetic Distance (GD) calculations from John show: 2 to David(CAMPBELL); 3 to Ron, Doug(GOODFELLOW), Tom and Mike(IRWIN); 4 to Joe and Martin; 5 to Earl, Roy and Michael; 6 to Doug(BLAKEY), David(TROTTER) and Patrick; 7 to William; the results showing an excellent match to the modal, with markers 389-2 = 30 and CDYa = 39 looking as if they will signify this particular lineage. 
GeneticDistance(Testee67Markers) At 67 markers the theoretical Genetic Distance (GD) calculations from John show: 1 to (F-42), Stewart and RF(Bob); 2 to Alastair; 3 to Michael(Simpson) and Mike(IRWIN); 4 to Geoffrey, Alexander, (Eckford:F-27), Joe, David(CAMPBELL), 8V8X3(Elliott), Charles(Elliott) and Z5AWP; 5 to (F-35); 6 to David(TROTTER), Patrick and Martin; 7 to Doug(GOODFELLOW), LE(F-31), Earl, Roy, Michael and GD; 8 to Doug(BLAKEY); 9 to William and Tom; two of these differences are values that only John(F-17) has for all of lineage 1 and can probably be taken as representative of the line of John and Jessie (Johnston) Fairbairn; (389-2 = 30 instead of the 29 everyone else has; CDYb=39, where the modal value is 38, although as a faster mutating marker this latter does show more variation within the lineage) NB although Joe (F-10) is shown as GD4, two of those differences are on the one marker, CDYb, some calculations would therefore say they were GD3 instead.
FT DNA's time predictor provides the following probabilities for John (F-17) (given no common ancestor within 4 generations) to Stewart (F-38) & Bob (F-34): 88% within 8 generations, 99% within 14.
The equivalent probabilities for Charles (Elliot) F-32 are: 59% within 8, 93% within 14 and 99% within 20 (included because of the results for the 111 marker tests below). 
GeneticDistance(Testee111Markers) At 111 markers the theoretical Genetic Distance (GD) calculations from John show: 3 to Stewart; 6 to Charles(Elliott); FT DNA's time predictor provides the following probabilities for John (F-17) (given no common ancestor within 4 generations) sharing an ancestor with Stewart (F-38) as: 83% within 8 generations, 93% within 10, 99% within 14.
The equivalent probabilities for Charles (Elliot) F-32 are: 51% within 8, 93% within 14 and 99% within 20.
