About us
This project was created to better understand the origins and history for a specific lineage having the
1. Longniddry, Scotland - remains estimated to be from approximately 1400 BC(BCE). Longniddry is a village in the
uncommon YDNA STR markers of YCAII 22-23, 22-22 or 23-23 along with a positive results for the
SNP A6119, in addition to other specific off modal marker values (see the Results page). Taken in
totality, these markers comprise a YDNA signature named the Central Irish or British Isles YCAII
22-23 Cluster.
The first matches found for this cluster all appeared to have surnames typically found in the Irish
The first matches found for this cluster all appeared to have surnames typically found in the Irish
midlands, hence the name Central Irish YCAII 22-23 however as more results came in, additional
surnames were found to match the cluster that appear to have an English origin, although those
matches may be of a more recent point of origin. One main goal of the project is to determine the
point of origin for this lineage, within the British Isles during and during the time period of 750 to
1100 AD.
When looking at all the matches to this cluster found thus far, we can estimate the common ancestor
When looking at all the matches to this cluster found thus far, we can estimate the common ancestor
for the entire group existed somewhere between 750 and 1100 AD. This estimation however is based
upon a fairly limited number of test results. As more matches are found and additional testing is
performed, we are optimistic we will see patterns develop that will hopefully point to a point of origin
for this group. It's also possible that further ancient remains may be found that match the lineage and
that could also help to better understand our origin within the British Isles.
**The L1066/CTS1202 SNP, shared by many and also found in our YCAII 22-23 cluster,
**The L1066/CTS1202 SNP, shared by many and also found in our YCAII 22-23 cluster,
has been found in ancient remains from the following areas**
1. Longniddry, Scotland - remains estimated to be from approximately 1400 BC(BCE). Longniddry is a village in the
East Lothians, on the shores of the Firth of Forth.
2. House of Binns, West Lothian, Scotland - remains estimated to be from approximately 43 BC/BCE to 117 CE/AD.
The discovery of these remains is relatively close to the remains discovered in Longniddry, demonstrating a
presence in this area for hundreds of years going back to approximately 1400 BC/BCE.
3. Oland, Sweden - Viking remains estimated to be from approximately 829 AD(CE),+/-57years. Oland is the 2nd
largest Swedish island and is located in the Baltic Sea.
4. The Bishop’s Seat, Kilteasheen, Roscommon, Ireland The Bishop's Seat -Kiltasheen, Roscommon, Ireland, estimated
to be from approximately 600 to 1300 AD.
5. Eperjesvölgy, Püspökladány, Hungary - approximately 1035 - 1065 AD.
A6127 - There does appear to be an existing A6127 descendant who branched away from our group at A6127, it would be good to hear from this person because all details are unknown. A6127 matches not matching any other snps in our A6119 group are very distant matches, only slightly more closely related than our L1066 matches. We are only aware of this one individual at this time. Update 6/2025 - The A6127 SNP predates our acquiring the YCAII mutations so it is generally deemed beyond the scope of the project goals. The focus will be on A6119 and its descendant SNPs.
A6119 - No ancient remains yet published as positive for this snp, this future discovery could prove very meaningful for the group.
