Only one member. yDNA SNP tested initially (on Ancestry) and that to SNP branch P312. MorleyDNA analysis of the yDNA SNPs tested shows negative to sub-branches -2b (R-U152) and -2c (L21). Really need deeper SNP testing like BigY as SNP Pack coverage is shallow for P312.
The tester has since done y111 STR markers. Although no matches at that depth, the y67 match list is crowded with more distant matches (GD of 5 to the cut-off of 7). Of those now 40+ y67 matches, over 14 have BigY tested. A majority of those BigY results cluster inside S17075 (also labeled R-S1388 at yTree and Y17483 at yFull). This is a terminal haplogroup on yTree and yFull but contains 21 leaf nodes in FTDNA's Y Tree as of Jan 2018. Most of these BigY results are tightly clustered within Z17121. So Z17121 is the likely, predicted subclade for this group, based on these closer haplotype matches.
Note that we had earlier predicted this group to be down R1b-DF27. This new designation is down R1b-DF19. Which was really equally as likely when the older prediction was made. C'est la Vie.
BigY testing in Fall 2018 has provided a terminal two steps down from the earlier haplotype predicted haplogroup of Z17121. The family group is now down to Z17121 -> Z17122 -> Z30496*. His closest matches are showing a branch or two below that or branched off in parallel from Z17121. See the second FTDNA chart to the right for this update. yFull and yTree have not really had any changes to this area since last reported and linked above. yFull predicts Z17121 formation around 1800 years ago. So the many (that is, OSM) matches at y67 are from around 2,000 years ago or less. Still pretty distant. Showing that the y67 markers are more stable for this clade of the phylogenetic tree and thus explaining some of the OSM issues.
