TessAkaBridgetTheFidget I had a similar problem in my youth - (go back to where you came from) exacerbated when I had an 'afro' - and not helped as I (black hair brown eyes) have 3 blue eyed siblings, two of whom had blonde hair!

My grandad's best mate was black - His father was 1st generation from Barbados - but his mum's family had been here for over 5 generations!

My brother has agreed to have the DNA teat done, so now I have just got to wait for it to come on special offer.

Meanwhile I have been able to increase my Scottish and Irish trees because of DNA matches.

Rollo Interesting to hear that post ice age Brits had dark pigmentation skin. Perhaps "my lot" have been here for ages....... despite being told to go back where you came from by other locals.

Seriously, I would be delighted if it DNA could show pre Roman occupation genes. Would love to have an idea which tribe I came from. ( I can but dream).

My father never knew who his father was (neither did his sister). We don't even know his father's surname - but have an inkling.
I decided to trace my father's lineage through his mother - after all - the mother is usually the mother - the father (even if there's a name on the certificate) could be anyone!
I was lucky - dad's mum was Cornish, Cornish Parish records are free online.
I've managed to go back to the 11th century on dad's heritage, through his mother and mainly the female line- he was the first of his lineage to leave Cornwall! A few Normans are there - but they soon became Cornish too!
Dad's 'potential' father was also of Cornish heritage - even though he was born in Barrow -in-Furness and moved back as an adult - Cornish tin miners moved there to mine copper when the Cornish tin mines closed.

I suppose, what I'm saying, is look at alternative reasons for people not being where you expect them to be.

ZZzzz,
In answer to your question, the answer is probably YES.
For the same reasons that have been outlined by others on the thread, your brother will have DNA matches that you don't.
Most likely 3-8 cousins

I don't have any siblings who tested but, I do share DNA with siblings ( brother and sister who are both my 1C1R)

I have individual matches with the brother who do not share with the sister and vice versa.
However, I can prove that most of these shared matches, whether shared with the brother, the sister, or both, do descend from the same, direct ancestors that we all have in common.
Most are 3-5 cousin range

By entering both of my 1C1R DNA onto DNA painter, I can see what we all have in common
I can also see the segments that I share with one and not the other.

I haven't had an email yet but on checking I see that my Ancestry ethnicity estimate has been updated.

It was very similar to yours Jem, at 64% English/Welsh/NWE and 34% Scottish/Irish plus 2% Germanic European. Now it is 77% and 21% and 2%. For the 77% it does include a mention of Kerrier and East Cornwall as the main areas..

Just had an email from Ancestry advising me that my DNA result has been updated ...

SO! I'm no longer 63% English, Welsh & North Western European and 37% Scottish & Irish

I'M NOW 72% English, Welsh & North Western European and now only 28% Scottish & Irish!


So- am I now more ENGLISH? or :-S WELSH? :-S ;-) :-D


Of course I do know that my DNA is exactly the same as it always was and that it's their way of evaluating it that has changed! :-|

"contributed 0.1% of your DNA"

Inheriting DNA in that way is not at all what happens, it is not some sort of parallel to handing down money with succeeding generations getting less and less. In practice there is not much DNA variation at all!
There are still large sections of DNA sometimes called JunkDNA which are important but the role is not very well understood.
As for the rest it is somewhat like a giant kit of bits with data and instructions with which to build a creature. As an example all animals have the same base genes for vision such as OPN1LW.
The variation on which @ncestry and other dna kits rely is marginal.

Interestingly DNA analysis shows that the original post ice age Brits had dark skin pigmentation. The Romans were unfazed by skin color and as a result many people of darker skin color came to live in the British Isles long before the notorious slave triangle got going.. This can show up as unexpected matches to north Africa and the Middle East which have not been expressed in generations.

The chances of a recessive gene being expressed are of course down to Mendel's Law.

Using the Ancestry dna matches I was able to find a group of brothers all who may have been OH,s secret grandfather. It was only when my BIL did a test with my heritage that we found out which brother was the culprit.

It might be worth looking at downloading your data to one or more other sites but some of them now charge.

Your brothers DNA will throw up the Y CH which he wont inherit from your mother,so that will almost take you down your fathers route,but there is nothing to say that he may have some*genetic* from the Frame line that you don't have ,,,,,,,any glimmer is better than none at all...for a few £ I'd say go for it...…….wait till they have an offer on,,,,,

The trouble I’m having is my Mother was born illegitimately, the only other possible link is my step uncles son in Australia but he is on my mothers side, my mothers fathers surname is Frame and so far haven’t connected to them yet. ??

It is Ken,,,,you have to have a little insight to DNA profiling to get an idea how its transmitted down a lineage,,

When its put as,,2% xyz,,,,in real terms that 2% has been mailnly found in areas of ABC,,,,,we have no idea beyond a certain timeline where that 2% has been introduced.....

.unless like the ones who claim to have got back to Adam by written proof beyond doubt;-) :-D :-D :-D.

Thanks for that link Kay. Anyone who is puzzled by their ethnicity results should read it to see how the estimates are calculated.

If you go back 10 generations (about 300 years) then there are 1024 ancestors who on average have each contributed 0.1% of your DNA. However the DNA of some may not have been passed on and others may have passed on much more. Go back another 300 years and the average is one millionth each.

I have no idea how I am related to the children, Sylvia. Obviously through the father who is Spanish (Mum is English) so a big mystery to me. But my Paternal ancestors were all seaman ;-)

You are correct JemimaF.

I have had some DNA matches with people I know I'm related to. And some matches with descendants of people in my family tree who I didn't know of. No Nigerians though.......

One of the sites I uploaded my DNA to did a check to see if my parents were closely related (they were), and it came up correctly, so matching does seem to work, somewhat.

"We all have 100% DNA and inherit 50% from both our mum & dad.
If there were 100 cards and we were asked to pick 50 out, the 50 we pick will be different from the 50 our brothers & sisters choose.
Our children cannot inherit DNA we don't have though"


The scientist in me now asks .................

she does not have the DNA that her children share with you

Therefore you must be related to their father who gave his DNA to the kids.

Is that so?

If not ............... how did the children get the DNA they share with you if they didn't get either from their mother or who was thought to be their father?

I had mine done on Ancestry last year. I am still struggling to understand all the ins and outs of DNA.


Someone who's children (but not her) share my DNA explained it to me this way...

"The best analogy I've heard on how we inherit DNA from our parents, is the pack of cards description.

We all have 100% DNA and inherit 50% from both our mum & dad.
If there were 100 cards and we were asked to pick 50 out, the 50 we pick will be different from the 50 our brothers & sisters choose.
Our children cannot inherit DNA we don't have though"


I think this means that although siblings will share a lot of our DNA they will also have different DNA. Luck of the genetic pool draw.

But I may be wrong! :-D
