This subclade of R-U152 shows up consistently among men named Collins in County Cork, Ireland. The subclade in general has a notable presence in West Cork. These Collinses are different from R-CTS4466 Collinses, the latter haplogroup more well-known, more common in Munster, and likely a more recent arrival. However, the project is blessed with far more FGC4166 members so we know more about them.
The dataset on this page is challenging. It has only 7 records of expert level participants as of late 2022. Up to this point in time, the project has hypothesized that marker DYS389II (#12) might be used to split members in these clusters into more recent lineages. Now, that hypothesis is looking more precarious. For this reason, the separate clusters have been merged back into one. Some older analysis has been moved to an archives page so that members can refresh their memory with any previous thinking.
Since the last update, some more members in this dataset have done advanced Y testing. This has been an enormous help. A year ago we didn't know much about what lay ahead after FGC4166, now dated earlier than 2000 BCE. Now look at what we have! The results have forced some reconsideration of the data. Despite the new information, significant gaps nevertheless remain, for example, the roughly 2500 year gap over the Bronze Age through the Iron Age and after. We are now aware of a split that occurred, probably some time during the second millennium. Apparently, the paternal line ancestors of these members lived within reasonable proximities to each other, apparently for many centuries. This gave time for their SNP stream to split and for each branch to spread.
The Corca Laidhe project is investigating the possibility that the FGC4166 Collinses could have been the O'Cuilin as written in the Genealogy of the Corca Laidhe. That project hypothesizes that these Collins men are descended from an older more indigenous population in southern Ireland, whose ancestors came from Central Europe to explore Ireland for minerals such as copper. Cork and Kerry have ancient mines as well as more modern ones. This sounds applicable to R-U152.
Project members in this now merged cluster show relationships to each other, though they seem somewhat distant overall. Subsets of these members do not share obvious STR mutations that could signal a closer, more recent relationship. No real correlations have been found between STR mutations and terminal SNPs.
This data is in Cluster 1810 inside the FTDNA results.
The locations pinned on the first map are based on the estimates provided at Scaled Innovation (Rob Spencer). Collins men carrying the two terminal SNPs - FT394701 and BY121592 - are geographically dispersed and intermingled with each other in County Cork.
The dark blue dots on the map below approximate the ancestral origins of expert level participants. As of October 2022, two participating members carry one terminal SNP, two members carry another, and four have not done advanced Y testing. Terminal SNP labels won't appear on the map until we know more.
Haplotype Table
FTDNA reviewed the markers of #33477027, found errors with DYS437 and DYS438, and made the necessary adjustments. Haplotype Table 1, Genetic Distance, and TMRCA tables have been updated. A further review will be done when additional members in this cluster become expert level participants.
