Any experts here to help?

So DH Grandma is from country A
She arrived in The UK pregnant with MIL just after the war to be with DH Grandad who had (supposedly) got her pg just before he left. Grandad was from an insular farming family in Yorkshire who had lived there for generations
Grandma always hated people from Country B. We know soldiers from Country B occupied the area Grandma lived post war and Great Auntie who was always from there spoke about how the Country B soldiers were “evil rapists”
Grandad and his family had a very distinctive look and DH Auntie and her daughters have it but not MIL or DH.
DH has just done his genealogy and he is 25% from Country B with NO English (his Dad was from country C and he is 50% from there)
I appreciate borders were more fluid in years gone by and Country A and B are quite close but we always kind of wondered if Grandad was biologically DHs Grandad.
What would other people’s conclusions be?

I’d group the dna matches and their common matches by genetic community (eg country A country B country C) and build hypothetical trees (eg if 1st or 2nd cousin with a tree, using their grandparents as possible grandparents) and test the strength of the hypotheses via thrulines if on ancestry - this takes a while but once it all lines up you’re away.

Obviously the family names of your matches are a great help too if comparing eg Spain/Italy, and some sites (23andme, myheritage) let you search matches by genetic community/region. I had a one in ten thousand hope of identifying my maternal grandfather but tracked him down very quickly this way.

UnFortunately there is only 1 match on there and it’s from his Grandmas side so not much use.
I dont think that if his real Grandfather was what we think he was DH would want to track down any matches from him
I do appreciate the help though

I agree with Ylfa on going through systematically.
There are various possibilities, not all of which mean the potential GF is a rapist (and even if he were, his children and other relatives etc would be blameless). eg: GF might not be solidly Yorkshire; or the other possible GF might have had a consensual relationship with GM.

When you say there's only one match, do you mean through Thrulines, or whatever it's called? Do you not have any second, third or fourth cousin matches on that side?

Thank you
Given a few other things I doubt if the mystery man WAS DHs GF it was a consensual relationship and I appreciate his family now would be blameless but due to the Country involved it would not be a great time to get in touch with them. Plus I imagine it would be hard for them to hear as well.
GFs family are from 1 small Yorkshire village going back many generations so we are pretty sure they are English (and there is literally 0 English on DHs profile)
The only matches he can see are his Mums cousin (from his GM side) but he’s new to this so maybe he isn’t seeing them all.
I will suggest he looks for more on the profile he has been sent

Bear in mind you don't need to get in touch to use people's DNA info.

Also, although it does seem likely from what you said that GF isn't the grandfather, I wouldn't assume GF's family are from one place without doing the research, as lots of "incomers" hide their ancestry.

His mum's cousins may actually know who his GF is. Often siblings know things that the children don't, and pass it down through the family.

I'm confused @Hoppingreen.
You write "....She arrived in the UK pregnant with MIL just after the war to be with DH Grandad who had supposedly got her pregnant just before he left........"

Had he been abroad in Country A and supposedly got her pregnant over there but the family now believe the baby wasn't his but as the result of rape ?

Yes that’s right.
Soldiers from Country B occupied the area GM lived in as the war ended for a while and while GM never spoke of it a Great Aunt did and she told some awful stories. GM always hated people from Country B .
British soldiers arrived in the area and took over from the Country B soldiers and I remember Great Aunt saying that they “saved” them (although B and England were on the same side - opposite side to country A)
To give even more weight to our theory DH has been in touch with a match he has found and it looks like they may be related via a Great Grandparent. DHs match is originally from Country B.
DH says he isn’t too bothered, (supposed) GF was a really lovely man and DH says if anything this makes his appreciate him even more

Also, the story was that GM came to The UK to be with GF and then got pg with MIL but few years ago we were at a family event and MIL had had a few drinks and said it would have been her parents x year wedding anniversary that day if they had still been alive. Later that evening DH said to me that that meant GM had to have been around 5 months pg when she arrived in The UK as they had married within weeks of her arriving
DH never asked her about it and probably never will

So if your DH is:

25% from country B
50% from country C

What about the other 25%?

Central European but more towards the East with a bit of Scandinavian

If his grandma is from country A, then surely that should be in the other 25% somewhere. Unless of course her DNA makes up much of the country B element. Because although she was from country A, you don't know where her parents and grandparents were from.

GM family were from A as far as we know and could be included in the Central European part that makes up the final 25%.
So it’s
50% Country C (DH father from there)
25% B
Remaining 25% Central Europe and Scandinavia ( could include DH Grandma)

Thank you to everyone who has posted by the way

Grandmas parents were definitely from A though as MIL talks about going back to visit the family village every summer and also visited a few years ago to see distant family who were still there.
Again a farming family who as far as we know lived in a small village for generations (although of course it’s not certain)

Have you gone through getting birth certificates? The grandfather from Yorkshire might have been adopted.

PS It might be easier to understand to name the actual countries.

We haven’t got birth certificates but as I said there is a very distinct look about that side of the family. There were 4 boys and 2 girls and they were all very similar in looks. At a funeral for one of them a few years ago almost everyone from that side looked very similar apart from DH (MIL didn’t go). MILs younger sister definitely has the look as have her children (DHs cousins). We are quite close to one of these cousins and if asked I am pretty sure she would do the Ancestry test and not tell anyone. I am leaving it up to DH whether he wants to pursue it

Probably but might be outing . Unlikely but as it’s a bit delicate I dint want to take the risk, sorry

It would be a bit of a coincidence if he was adopted from country B (which I think I can guess).
