No DNA from grandfather's ethnicity
« on: Friday 03 July 20 16:07 BST (UK) »
 ::)Would it be possible for someone who has a Jewish grandfather *with origins from Russia to show up with 0%,European Jewish on ancestry test

I show up with 12% .have a Russian Jewish great

Modifiedgrandfather .

I wonder if the person concerned may not actually descend from the man recorded on his father's birth certificate.

someone who has a Jewish great grandfather

You have said "grandfather's ethnicity" in the header, and "great grandfather" in the text - is that an error?

No oops sorry avm have modified

I mean its someone's grandfather
I gave example of amount of my ethnicity from 1 great grandfather

My mother has 24cm european Jewish ethnicitybecause she has a grandfather

The person whose DNA I'm looking at is related thru English side  to us but he also has a Jewish grandfather born London with family origins in Russia and south Africa his ethnicity doesnt reflect this

I think it very unlikely that a person with the descent you describe would have 0% European Jewish ethnicity found on these tests, so I would think there must be a break in the chain.

Yes avm it was a  slip up
Thanks for your confirmation of this opinion

I spent quite a while researching his tree but he's lost interest
Is it worth telling him my theory ?

I have experience of spending ages on an unrelated personís research only to find that he had lost interest - just at the time things started emerging that he wished he hadnít found out.

On something as sensitive as you suggest, I would recommend saying nothing at all unless and until he specifically raises it with you.

Itís tough, I know, to judge how to handle these issues.

I am not sure Ancestry is particularly good at detecting Jewish ancestry, 23andme may be better, but again, like Ancestry I think they only have Ashkenazi samples. Better to look at matches, in gedmatch as well if you can upload there.

Avm thanks for advice he may have lost interest because he'd already come to same conclusion

Melba no I don't know how to upload anything

I was rather impressed by Ancestry DNA they got it right for us 24% is accurate for 1 grandparent

A lot of our matches are 100% European Jewish I don't think Ancestry has any other definition

As far as anyone knows they only have samples from Ashkenazi Jews in the USA, so that is what European Jewish means as far as Ancestry goes. I think MyHeritage may have some Sephardic and Mizrahi samples. It is little more difficult with those populations vs Ashkenazi Jews as they are less endogamous, more diverse in their ancestry.
