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 originally named the Central Irish, later the
British Isles YCAII 22-23 Cluster.
British Isles YCAII 22-23 Cluster.
YDNA testing has verified the shared paternal ancestor found under the SNP A6119, which is currently
estimated to have occurred approximately 250 CE.
When looking at all the matches comprising this cluster, we can see 3 clear patterns. There is a line comprising
what are historically known as Irish surnames, there is a line historically known as Norman-Irish surnames and
there is a line known as historically English surnames. These various lines appear to mirror the Norman invasion
of England and the later Anglo Norman invasion of Ireland. The various lines appear to have split between 1050 AD
and 1300 AD, as demonstrated by the estimated ages for the various SNPs.

**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.
6. Winterbourne Kingston, Dorset, England - approximately 158 BCE - 58 CE
7. Winterbourne Kingston, Dorset, England - approximately 147 BCE - 61 CE
Interestingly, under a grandparent SNP of A6119 and L1066, the SNP Z2185, we find the following remains,
which support the proposal that some lineages found under Z2185 may have a Scandinavian origin. It does
not appear they found or are reporting what should be a terminal SNP for this individual since there should be
many additional SNPs under Z2185 to get to the the time this male lived, predating the historical Viking period.

Z2185 - Nymarksgaard 107529, approximately 666 - 774 CE. associated with the Medieval Scandinavia cultural group.
A6119 - No ancient remains yet published as positive for this snp, this future discovery could prove very meaningful
for the group. As of this writing, 2/21/2026, there appears to be quite a bit of ongoing DNA testing of ancient
remains so we are optimistic a match to our A6119 lineage will be found in the months ago, hopefully this year
