Here is a first draft of
Haplogroup R1b. I haven't modified the history for over a year, so I should re-read everything once and see if everything is consistent with my current knowledge. I should also make a new subclade tree.
There are substantial changes in granularity in the R1b-L21/S145 haplogroup. ISOGG is fairly up to date.

I will try to summarize the more significant subclades of R1b-L21/S145:
L513/DF1/S214 which has further suclades (in order of size) of L193, L705.2 and P66.
L513 is scattered across British Isles but reaches into Sweden, Benelux and France and is associated with the
11-13 Combo cluster. L193 is the largest subclade of L513 and has a preponderance of Scottish Border lineages
and surnames.
Z253 which has the subclades of L226/S168 and L554.
By the far the largest subclade is L226. It is noted as marking Irish III haplotypes and maybe associated with
the Dalcassian clans. Two Z253* people have been found of Iberian descent.
DF21/S192 which as the subclades of Z246, P314.2 and L720 and S190.
DF21 is scattered across the Isles and Benelux and Norway. The largest DF21* cluster appears to be null425 Clan Colla. (EDIT: added Clan Colla comment.) Z246 appears to be the largest SNP marked subclade and includes DF25/S253 underneath it.
S190 is new so there are some unknowns but it is downstream of DF21 and has been found in Little Scots cluster people and it is downstream of DF21.
Z255 which has the large subclade of L159.2/S169.2.
L159.2 is associated with the Irish Sea/Leinster cluster.
L371 which is associated with the Wales I 17-14-10 cluster.
L144
