Title: Cornwall and Devon DNA
Post by: brigidmac on Saturday 08 April 23 12:17 BST (UK)
Has anyone who has long Cornish Ancestry tested on ancestry ?

What does your ethnicity state
My friends father was from Cornwall and tne paternal line has been trace back to. 1700s
His results  27,%english +north European  ancestry breaks down his community as specifically from Devon and Cornwall
Sub division of kerrier Cornwall+eas Cornwall
Just From his father's side he has inherited
24 % Scottish  8%irish +2%swedish

Cont...
The 11 % English inherited from his mother doesn't specify a community but she is mostly Welsh and African

The father's mother  was born to a single mother whose line I ve also traced back to 1811
But thru lines are not showing

I already  thought  that this grandmother must have been born to a Scottish father

But with such a high Scots percent
maybe the great grandmother was also Scottish origins or adopted

Either way I'm interested in hearing what
Results . Cornish or half Cornish testees have had

Brigid, I'm currently away from home with a terrible wifi signal, but here goes...

Ancestry communities are derived solely from ancestors locations in the trees of DNA matches, in a similar way to Thrulines hints. So they have nothing to do with a direct analysis of your or their DNA as such.

Hence the reason that I and my brother belong to a number of USA communities, when we have no direct ancestral connections to the US at all. But our maternal GGF had several children by another partner before marrying our GGM. They all emigrated from the north of England to the US and we have numerous half cousin matches at varying distances with their descendants.

So Ancestry think we have US origins ???

I disagree I am not located in Latvia or Scotland
My friend is not located in Cornwall
We put names of ancestors before origins
Ethnicity shows up before you build a tree

It's getting more and more accurate
My mother's results originally showed some European Jewish now it's to specific origins
Many Americans especially attribute erroneous locations to their ancestors from pre 1900 Baltic's even if they know names
The ancestry DNa picks up the region

AS  far as I know Ancestry does not have a US
Ethnicity Apart from.natve American

My American relatives have Scottish/ Irish Welsh /English /European Jewish  ethnicity

Have you misunderstood how the DNA ethnicity works . It shows emigration of communities and locations where your matches live. if you look at maps but if you look at the ethnicity of your matches compared to your own it will be accurate
Title: Re: Cornwall and Devon DNA
Post by: brigidmac on Saturday 08 April 23 16:11 BST (UK)
Not relavant to Cornish post but this is shared ethnicity with a third cousin our common ancestors are Welsh
He has no Jewish European. Germanic or Swedish  which is why those are  blank I'm not showing his amount because it would reveal name but you can see the relative amounts in colour bars

The map underneath is green for shared ethnicities blue for my unique  ethnicities and yellow for ethnities he has + I don't

No I haven't misunderstood. Ethnicity is derived from DNA segments believed to be common to individuals descended from a particular region. How accurate it may be at any particular level is open to a degree of questionability.

But besides ethnicity, you also referred to a community of Devon and Cornwall. Ancestry's communities are derived from locations in common to the more recent ancestors of you and your DNA matches, and are determined from the location information in your and their family trees, for ancestors who lived in the same places over a similar period of time, not from any information in your or their DNA, other than the genetic autosomal matching that connects you and directs Ancestry's algorithm to run its trawl through those trees.

North American communities are certainly not restricted to indigenous Americans. One of the communities that my brother and I share is Ohio, Indiana and East Kentucky Settlers (1700-1975) which Ancestry describe as "The pioneers of German and English ancestry who crossed the Appalachian Mountains in the late 18th century".

In respect of which, Ancestry also say, "You, and all the members of this community, are linked through shared ancestors. You probably have family who lived in this area for years—and maybe still do. The more specific places within this region where your family was likely from: Southern & Central Indiana, Southwestern Ohio & Northern Kentucky."

As I say, my family have never been to or settled in any of those locations, but numerous half cousins descended from my GGF did emigrate to and settle in those areas. No-one from my direct line, certainly within the last 300 years, which Ancestry Communities are supposed to represent.

I may have mis worded about American ethnicity

Anyway I'm interested in people with well established Cornish identity and hope some will share how their results are described

I'm looking at the matches from friends paternal line but a lot don't have very large trees so I can't see where their ancestors lived .

Title: Re: Cornwall and Devon DNA
Post by: brigidmac on Saturday 08 April 23 20:12 BST (UK)
There is some confusion over ethnicity and communities because of the way ancestry worded it

Id like to know if other people have specific Cornish or Devon ethnicities such as this

My 74% English highlights Devon & Cornwall as one of two regions. All would have been from my mother's side her maternal GGM's family from Cornwall and her paternal GM's family from Devon
Title: Re: Cornwall and Devon DNA
Post by: brigidmac on Sunday 09 April 23 11:19 BST (UK)
That's interesting Petros
I'm going to post about names later some surnames keep recurring through different branches of the tree . VERCOE/VARCOE  + CROWLE /CROWL +versions of Tredigar/Tregida  particularly.

I think some surnames are specific to Cornwall

I've just learnt that ancestry group channel Islands + isle of man
ethnicity with Scotland at the moment

I shouldn't be surprised as Ireland and Wales used to be slotted together and are now shown as separate entities .

I will keep an eye out for Scottish ancestor just in case and be aware that matches Scots ethnicity may also be from channel Islands
Title: Re: Cornwall and Devon DNA
Post by: brigidmac on Monday 10 April 23 16:21 BST (UK)
Irish ethnicity can include channel Islands too

I've been given the name of the missing great grandfather a married man who had a long  term affair with the great grandmother I'm told

Adding his ancestors to tree and already finding surnames that show up in matches tree s ..

I have Kerrier community origins through Jenkin/Jenkins , Tresidder etc on my fathers line and Thomas on my maternal line

Title: Re: Cornwall and Devon DNA
Post by: brigidmac on Monday 10 April 23 20:18 BST (UK)
I don't know how far the Kerrier community stretches to
 known ancestors are mostly from st Austell Roche + st Stephan's

  distant matches with people  who have  Tresidder s 1770  from Constantine
& Ann Tresidder from st Neots

I have no known Cornish ancestry but have ancestors from the Dorset/Devon border. In Bermondsey London I have an ancestor with a rare forename that when found is found mainly in Cornwall but his roots seem to be from Staffordshire.

My 3xgreat grandmother born in Shoreditch in 1835 was, about 60% of French blood. It was her who married my 3xgreat grandfather whose paternal roots lay in Devon/Dorset.

I have Bray, Yelland and Trethewey amongst others my x 2 great grandmother was born in St Stephens in Brannel. https://www.genuki.org.uk/big/eng/CON/StStepheninBrannel

Ethnicity is just East Cornwall, no other info

Some excellent personal tree research for Cornwall and Devon. https://www.lizandstu.com/surnames.php

Upload to or test with Living DNA. They claim to be able to narrow down to more precise regions within the UK. Surname distribution can do a similar thing as some surnames are more concentrated in certain regions..

If the families were in Cornwall/Devon for millennia a Y-DNA test might be worth consideration.

It is not advisable to take too much notice of the ethnicity percentages, particularly the tiny percentages.

Caz i.ve just clicked on the link you gave

Indeed excellent research and many of the surnames of  people I'm interested in
Love the charts too.

It would be great to do that for my own family

Although I suppose its based on family trees so wouldn't include names from bio parents

Ruskie when the classification is right even small ethnicities can help identify which ancestor a DNA match connects to

I'm helping someone with very varied DNA specific to each person.
It's a bit complicated to explain

I too have Cornish ancestry. In fact, my maternal grandfather has 100% Cornish ancestry, proven without reasonable doubt. Kerrier seems to be the default location, despite my ancestors coming from places nowhere near there. And how does that reflect on my paternal Devon ancestors?
Title: Re: Cornwall and Devon DNA
Post by: brigidmac on Tuesday 11 April 23 11:44 BST (UK)
Pine I think that shows that a lot of Devon people have Cornish ancestors and also that the definition of Cornish includes Devon

This what ancestry says
Title: Re: Cornwall and Devon DNA
Post by: brigidmac on Tuesday 11 April 23 12:01 BST (UK)
I've just learnt to use the more detailed DNA matches communities it's very useful when looking at matches with no trees
For example here's subject with Cornish born father
1st match is his father's cousin who has his Kerrier ethnicity but also Devon
+ East Cornwall isles of Sicily which he does not ...

The next is an unknown connection one who like the other shared matches   has Kerrier

Knowing the regions that a match does not show might be just as revealing as what they do show pine if your maternal and paternal  2nd or 3rd cousins tested you might pinpoint which ancestor  had most Devon

Florence YELLAND s daughter wilmot Hicks married Thomas TRETHAWAY B 1735
Daughter Elizabeth married into hisVARCOE/VERCOE line their descendants lived at st Dennis early 1800s

A William.BRAY 1877 from Truro Cornwall m Mary Jane  BINGLOW  related but not direct ancestors

First name is Parmenas. Born 1716 in Bermondsey, Parmenas Jerome, son of William and Mary. Luckily I found his dad's apprenticeship records as a felt maker which say he was the son of Robert Jerome of a parish on the Staffordshire/Derbyshire border. Parmenas' mother was Mary Mitchell who wed Wm Jerome in 1703. Maybe she had Cornish blood or they just liked the name.
