Title: Shared Matches below 20cM
Post by: ikas on Thursday 18 December 25 10:15 GMT (UK)
Just back from a break so I have not looked at my match list for about a week. Am I correct in thinking Anc have recently changed shared match lists to include shared matches below 20cM? Is this a new development that is being rolled out or is everyone now seeing shared matches below the previous 20cM cut-off?

I've got matches as low as eight.  It's increased my total number to over 22,000.

I rarely look beyond the first 100.

I'm also getting the 8-19cM shared matches without having ProTools. This previously required a ProTools subscription. It seems odd that Ancestry are not making us pay for this. Christmas spirit?

I think matches have gone down to 8cM for a long time but shared matches had a 20cM cut-off. I now have shared matches well below the previous cut-off and I am wondering if this is a new development that is being rolled out or can everyone see shared matches below 20cM.

I don't have ProTools either. Weird that Anc have not said anything about this. If this is permanent then it might be significant in identifying some of my unknowns.

I wouldn't be too surprised if it was a foul up at their end and see it vanish before long.

Make the most of it, it is Ancestry after all.

I missed the 'shared' bit!  Yes, I can see sub-20cM shared matches.

That's a shame, I made good use of it while it lasted!

Is anybody else having a problem looking at Common Ancestors?  I cannot get past the first page.

The 20cM shared match threshold hides so much it can really stop research stone dead.

I have a mystery 42cM match, he shares 604cM with 'SC' so I see them as shared matches on my account but I only share 15 with SC so the mystery match uses his account but doesn't see the connection. He also misses other matches to SC because of the 20cM threshold.

Thankfully we shared our dna results and I've been able to identify 7 mutual matches so far that the 20cM threshold manage to hide even when analysing match lists of each person individually. The papertrail of my mystery match doesn't line up with the DNA and I suspect an NPE somewhere. All 7 matches trace back to the same common ancestor which seems to confirm my suspicions but had we not shared our results my mystery match would still be in the dark.

I think that Ancestry has updated their system a bit.

If I have a Thruline or Common Ancestor that has a suggested pathway that does not compute I add the related DNA Match to a Mystery Group and add text “Odd Thruline” to the Matches Note.

Since your post I have revisited three such Matches and each now has a Thruline that is now valid.

Yes, I am now getting all the Common Ancestors again and a few new ones.
