Looking at the Clan Donnachaidh project, Robertson I, Group AE; there are two additional haplotypes grouped with M253, A4600 and YFS320376. I assume these are more detailed subclades but I can find no additional information confirming that. The Haplotype I chart at eupedia does not seem to show these subgroups.

Well, they seem to be new SNPs perhaps private SNPs amongst these Robertsons? They are also members of the Clan Hamilton DNA project. They are part of the I1-M253>L338>A376 group. A376 seems to have a decent spread from Scotland, Ireland and maybe parts of England (IIRC). I-A376 has a formation date of 1300ybp according to YFull and a TMRCA of 800ybp.
