After Tim McEvoy pointed out some other possible Cland Cathail surnames under the R1b-FTA43254 clade, I took a more detailed look at it. With the data we currently have, it appears that R1b-FTA43254 MAY be the Maicne Artgaile, the sons of Artgal, son of Cathal, son of Muiredach Muillethan. Then its two (2) subclades MAY be:
- The R1b-FT185820 subclade might be the descendants of Cináed son of Artgal.
- The R1b-FT62545 subclade or some combination of its phylogenetic node variants might be the descendants of Colla son of Artgal.
This will decidedly support the conclusion that the R1b-FGC5939 clade is the Maicne Eócháda Tírmchárnai. The question that still remains is whether the appellation of Uí Briúin Aí was originally applied to the Maicne Eócháda Tírmchárnai or whether is was possibly first applied to the R1b-Y166841 Maicne Cathail, the sons of Cathal, son of Muiredach Máel. This is the parallel clade to the R1b-A260 clade that is certainly the sons of Fergus, son of Muiredach Máel; and R1b-Y166841 is where the O’Conor Don gentleman is located.
This is a very labyrinthine genealogy because there is a Cathal, son of Muiredach Máel, (R1b-Y166841) and then a few generations later, a Cathal, son of Muiredach Muillethan, descendant of Fergus (R1b-A260). It is suspected that POSSIBLY these two (2) different branches became conflated, especially since both branches have Ó Conchobair and Ó Flannacáin families.
