53
FTDNA “Walk the Y” Extended SNP test over 100,000 bases in 2009 10 Irish Type III men contributed $75 each to have a member tested 52
54
FTDNA “Walk the Y” Extended SNP test over 100,000 bases in 2009 10 Irish Type III men contributed $75 each to have a member tested Kevin O’Brien selected as he:- –Matched the Irish Type III modal at 25 markers –Was an O'Brien, the principal family of the Dalcassians –Could demonstrate his pedigree originated in Co. Clare, Ireland –Had tested 76 markers 53
55
New SNP found – L226 At position 19048724, Thomas Krahn found Kevin O’Brien to be derived “T” rather than ancestral “C” He named this SNP, L226 54
56
Was L226 Definitive for Irish Type III? L226 available to order – October 2009 55
57
Was L226 Definitive for Irish Type III? L226 available to order – October 2009 Three possibilities:- –L226 is a 'private' marker found only in Kevin O'Brien and his immediate family (perhaps back 100-500 years). –L226 is a defining marker for the Irish Type III cluster and appears in no other clusters. (so perhaps 800 - 1,200 years old) –L226 is downstream of L21 but occurs more generally, across several clusters. (Perhaps 1,500- 3,000 years old) 56
58
Was L226 Definitive for Irish Type III? L226 available to order – October 2009 Those with Irish Type III signature all L226+ Those non-Irish Type III all L226- 57
59
L226 is Definitive for Dál gCais L226 available to order – October 2009 Those with Irish Type III signature all L226+ Those non-Irish Type III all L226- L226 is shown to be defining for the Dál gCais 58
