DNA LineagesDavid Fairbairn (F-9)
#1420
| Father | John Fairbairn |
| Mother | Frances Stefani |
| Lineage (Testee) | David was found to be part of Fairbairn Lineage 1d, with closest match initially to Doug (F-6), subsequently updated as being 1 step closer to Joe (F-10), see here for chart. |
| Researcher (Researcher) | David is researching the line of John Fairbairn **. Email: David (email current as at Nov 2008). |

| GeneticDistance (Testee) | At 12 markers the theoretical Genetic Distance (GD) calculations from David show: zero to Doug, Tom, David, Joe and (F-8); 1 to Earl, Roy, Martin, William and Doug. |
| GeneticDistance (Testee37Markers) | At 37 markers the theoretical Genetic Distance (GD) calculations from David show: 1 to Ron, Doug(GOODFELLOW) and Tom; 2 to John(JOHNSTON), Joe and Martin; 3 to Earl, Michael and Roy; 4 to David, (F-8) and Doug(BLAKEY); 5 to William. |
| GeneticDistance (Testee67Markers) | At 67 markers the theoretical Genetic Distance (GD) calculations from David show: 4 to John(JOHNSTON) and Joe; 5 to Doug(GOODFELLOW); 6 to Martin and (F-8); 7 to Roy and Earl; 9 to William; Although David belongs to the second "clump" of the overall lineage 1, ie has a 391 of 10 and 520 of 20, the value for 570, the other (faster mutating) marker showing a distinct pattern is 19, which he shares with Roy, Earl, Martin and Joe of the first "clump". |
| Summary (Witness) | We now have the preliminary dna results in for William (F-12), a documented descendant of John A Fairbairn Snr of Stillwater, Washington Co, MN, with Bill is indeed showing as an excellent match to Roy (F-3), the descendant of John's uncle William (phew!) The relationship to the other side of the Hoquiam triangle is rather murkier however as the representative of the Sunderland side of the triangle, Joe (F-10), belongs to "clump 2" of lineage 1. Still related, but how? With the full 67 marker results in, it rather looks like the 3rd side of the triangle represented by Joe (F-10), is showing marginally closer relationships with the lines of Thomas Fairbairn (marr. Elspeth Redpath), John Fairbairn (marr. Helen Campbell) and Trotter (marr. Jane Fairbairn) Fairbairn) lines. The expected relations above come a close second. The stated Genetic Distances of 5 for the lines of Thomas (REDPATH) and John (CAMPBELL) and 6/7, the John (FLINT) lines, can probably be marked one less because of the faster mutating markers involved. |
