Further analysis of NextGenSequences at YFull (see yfull.com/tree/J-M205/) combined with results from scientific studies (SNP, VCF & BAM results) has revealed a more consistent and hopefully informative basal substructure for J-M205 (see tree.j2-m172.info/?Hg=J2b1) then what was available at the latest major update: J2b-M205>PH4306: a little substructure for this isolated lineage.
See also yfull.com/tree/J-M205/
It seems likely that the many remaining J2b1-M205* samples will define further basal structure (indicating a rapid expansion of M205 after a long time without modern Y-Cousins).
EDIT: further analysis and discussion with FTDNA led to the conclusion that CTS1969 is the parent of CTS5338 and PH4306 (and YP13).
Regarding origin and expansion beside the YFull YTree v4.09 M205 TMRCA 5500 ybp we have two telling ancient DNA samples which seems fortunate for M205:
2489-2299 BC Early Bronze Age North-Western Jordan (‘Ain Ghazal, sample I1730/AG_84_3083_116) in Lazaridis et al. 2016 is J2b1-PF7331(xPF7312);
100-300 AD exogenous Roman era York (sample 3DRIF-26, likely Middle Eastern origin) in Martiniano et al 2016 is J2b1-M205
So the most likely M205 expansion origin seems to be the Western Fertile Crescent. For the subclades CTS5338, Y22524, CTS10179 +13 seems from Iberic Middle Ages, YP13, YP51 +4 is probably not much younger then M205 and still of Fertile Crescent origin while PH4306, {Y22075} is only slightly younger then M205 and likely has the same origin and expansion.
