DNA confusion

[decor]

I manage both mine and my mother's account.

My mother has a 162cM match with someone, let's call her Pam.
Pam is her 3rd cousin once removed through Pam's grandfather's paternal side.
162cM is quite a lot for such a match BUT it seems my mother is also more distantly connected to Pam's grandfather's maternal side as well.
Either way, it seems high to me.

I suppose the even weirder bit is: I don't match with this person at all!!!
A 162cM with my mother, but she's not even on my list.

That just doesn't add up to me!

Just a quick question do you match both your maternal grandparents sides via DNA not trees .
It is unusual

Yes, I have matches for all year of my grandparents, as does my mother.
Maybe I should e-mail Ancestry?

I think this kind ofanomaly can happen when someone inherits from two sides .
It just means you haven't inherited enough of that family's DNA to show as a match it doesn't mean you don't match at all but maybe under 20cm so not showing as shared match

Thanks for your reply. It's not just that it could be a shared match under 20cM, but I've searched for that person in my DNA list, which I think included matches from 8cM and up. I quite enjoy all the intrigues genealogy throws up ha ha

Me too .I'm from Leicestershire and know
Both Turi King and Alec Jeffries experts in DNA

I'm a great believer that ethnicity can solve some of the mysteries .

Working on a strange match myself where only common ethnicity is Congo ! 2 percent for one 31 percent for the other . But I suspect
The Swedish + Norwegian ethnic amounts or European and Scottish may come from same ancestor .

Have any of your mother's other relatives tested ? Sometimes a male relative has stronger matches for exams your brother nephew or own son could match this person

DNA matches are funny things. OH doesn't show a DNA match to a friend (J) we know is related. However, recently a new match (S) for OH turned up and we were easily able to figure out the connection. I've been comparing notes with S trying to sort out more matches in common & expand the family tree back another generation so I asked if they share any DNA with J. Yes, they do but OH doesn't although they are all related.

Aga When you 'know" they are related are you absolutely sure was anyone there at the conception ,births s or hospitals in each generation to check babies werent switched

How close is the relationship   ?
The further apart in generations the more scope for discrepancy on paper tree and or DNA lack of match

Births in those days were at home so a baby switch was extremely unlikely. OH & relative J share numerous matches that confirm family records so it's extremely unlikely that they are not related, it's merely that DNA less than 7 centimorgens won't show up in results.
