Is this possible

[Pheno]

Struggling to find anywhere in my basic dna book that tells me if this is possible.

Both myself (female) and my daughter have tested at Ancestry which confirms a parent/child link.

A new match for my daughter today shows a double dna match to ancestors of my maternal grandmother, one on my grandmother's maternal side and the other on my grandmother's paternal side.

The paper trail for both my daughter and the match shows the same people, one at 6th cousins and the other at 8th cousins.

I don't match dna with this other person at all. I know my daughter is mine.

I understand that I won't have passed all my dna to my daughter but whatever she has I should also have shouldn't I.  If that is correct then why do I not have the same double match at a closer level.

Is this something to do with recombination?

Any explanation gratefully received.

Thanks, Pheno

suggests that you and your daughter's father come from the same stock once you go back a few generations.

Gedmatch have an 'are your parents related' test. It might be worth uploading yours and  daughter's results to that site and run the test on both samples.

If you upload your daughter's DNA to Gedmatch you can do the test on it which tells you if her parents (ie you and her dad) have a common ancestor somewhere in her tree

Ah snap!

I did mine a while back, David, that's why I knew.  Mine weren't.

Thanks for those responses.  We are both on Gedmatch so I will run test and see but my husband doesn't have either of these lines in his ancestry and neither is he a dna match to this other match.

Added:  Have just run test and her father and I are not related.

I feel that I may have confused the issue here somewhat but I have now followed this through further.

It seems that there is somebody who has had their own dna tested and my daughter has a dna match to both her maternal grandfather and her maternal grandmother.  So they were not related to each other either but my daughter is related through both lines, as a 6th cousin in one instance and an 8th cousin in the other.

Is this unique?

Pheno,  When you use the word "her" are you referring to your daughter or to the person who has also been tested? I'm not being pedantic it's just not very clear.

No

I have a link through father's father's mother and  my father's mother's grandmother discussed here:

The cM suggests a 2nd cousin but we are actually twice 3rd cousins
