*****Scottish Gaelic type 1, (Niall of the 9 Hostages)**** This DNA pattern is well-known to DNA researchers as the DNA pattern associated with Niall of the Nine Hostages (N9H), who was High King of Ireland from 376 to 405. Many of the most important Scottish and Irish Chiefs claimed direct-male-line descent from N9H, including the MacAulays of Ardincaple and the McAuleys of Westmeath. Five men in the MacAulay DNA study had this pattern, all of them apparently of Scottish or Scoth-Irish ancestry. D.J. Macaulay, M.P. McCally, and D.J. McCauley had identical DNA results for the 12-marker test. D.J. and M.P. also took the 37-marker test and had 5 differences at the 37-marker level. D.J. and M.P. believe their ancestors are Scottish or Scotch-Irish, but don't yet know which ancestral clan they are from. *The FTDNA Time Predictor estimates that it is 80% likely that D.J. Macaulay and M.P. McCally had a common male ancestor 500 years ago, (I have been contacted by the MacGregor Clan, and we discovered that a few of the McGregors had the same FTDNA-12 pattern as MacAulay SG-type 1*. There are several theories that could explain this and more research should be done in this area.) Because N9H had so many descendants, this DNA pattern might be descended from more than one McCauley Clan. Matthew McCally is researching a possible linkage to some of the native clans of Northern Ireland. *
