ANALYSIS

Aug 2022 (N=186)

DF63 cluster (from 2017 entry)
In Cornwall, all of the very early DF63 branch of L21 belongs to one cluster, plus a few more members of a rare parallel haplogroup
This cluster is the  L21>DF63>BY592>Z16246>Z17553>BY3070>FT72783>BY3004>BY7782>BY7789>BY7774>BY36126

From BY7782 on, (late Bronze Age) , is British. BY7789 from the mid-Iron age is mainly Cornwall/Devon
It now includes Vincent, Carlyon, Hicks, Coombs, Trengove, Hammett and Jobes; also Pearse and Passmore of Devon, and likely others. 

The parallel haplogroup is DF63>BY592 > z16245>Z16246>Z17553>BY3070> FT72783>BY3004> BY7782>FGC36434>FGC36445>BY142727>BY190087,
It contains Mitchell from Warbstow, along with Congdon (Devon) and Harris

This juxtaposition inclines us to think that this DF63>BY7782 is actually Bronze Age SW England.

Dec 2019. 

Our first N (Y5611 Rurikid cluster, WALLs of St Just and Worcester are only ones in Isles. Rest are Swedish/Finnish with one Russian
Second U152 cluster, this one is much older, Bronze Age, probably arriving as part of the Continental Atlantic trade like DF27.

Nov 2019 (N=157)

New clusters R-U106, Z7>>FGC924, and within Z156>DF98, FGC13335 and FGC1135

R1b 78.8%
R1a 3.3%
I1 7.3%
I2 4%
E-V13  4%
GJT 2.6%

 
P311- 2.0%

P312 53 %

P312* 3.3%
L21 30.5%
DF27  15.9%
U152  3.3%

Main difference from previous - fall in I, rise in R1a and P312, considerable increase in minority R1b

Mar 2017. Third summary
166 valid members  have taken DNA in CORNWALL. The folowing is from L21 paper


Main things to note:

• Cornwall has the highest R1b, because it is at the intersection of range of L21, U106 and DF27 (some parts of Ireland are higher)
• Cornwall is low on 'invader DNA' - EGJT and U152 from France, I1 from Scandinavia, R1a from northern Europe
• Cornwall is low on indigenous I2, since it was probably heavily colonised by the R1b Beaker people around 2500BC
• Like the rest of southern England, Cornwall is high on U106 (but it declines from East to West across England). Brabant or Kent are probably the source, since concentrations are highest there.
• Not much L151*, probably Mediterranean

Clusters identified are:

• L21>Z253 much higher than in Devon, wide range of 'old subclades' Probably the source. Possibly also for Z251 and other 'Atlantic subclades' like S1091, 
• A lot of early L21>DF49 and L21>FGC11134 - possible source of later big Irish subclades
• L21>DF63>BY542 cluster (West Country), about 200BC; Two Cornish branches - Hicks/Trengove and Harris/Mitchell
• DF27>L617, big cluster, probably the source of this very early split
• Cluster of P312>Z30600 very early P312; other P312 branches A9439, Z28589
• Earlier R1b - L23- (PF2362) L51* (Z2118), P310*(A8053)
• Cluster of Iron Age P312>U152>>CTS11381
• R1a 'Drake' branch BY25522
• Yet to analyse U106; generally later

 
Sep 2015 Second summary of results

The R1b Backbone Test has finally allowed us to analyse our most important haplogroup, R1b. The most surprising result is that we have almost as much R-DF27, the Iberian subclade, as we do R-L21, the 'Celtic' subclade. This probably represents multiple incursions from the Continent (Spain and Brittany) over thousands of years.

Some of the unusual results we have are 

- two R1b-L624, an ancient branch of R-P312 going back to the early Bronze, the time of building of Stonehenge.

- A R-P312** and a R-U106*, unknown branches of these main haplogroups  


Jan 2015. First summary of results

Of these, eight are I (about the same incidence as the rest of Great Britain) and five are "rarer" haplogroups (R1a E G J  Eastern R1b). This gives a little over 80% R1b, similar to Ireland.

The R1b is quite mixed. About 2/3 is P312 )and 1/3 is U106. The latter is a little higher than the English average. 

We have four R-U198, a very old subclade of U106  largely restricted to Britain.
 
The numbers in CORNWALL are still too small for statistically significant results - we are aiming at about 250.
