Signed up for Pro Tools.
On my Wife’s tree her highest match is 187cM and is a known 1C2R on her Maternal side.
The next Shared DNA match shares 38cM with her and her 4xGGP’s is their MRCA.
Now this 38cM match also shares 29cM with her 1C2R but this 38cM match is on her Paternal side.
Now her Paternal side is Lancastrian for centuries and the Maternal side via her Grandparents is Dorset for centuries so there is no chance of Pedigree collapse occurring.
Already Pro Tools has thrown up interesting results in that the 1C2R is related to my Wife via his Mum and his Dad is also related to my Wife but we have never found where, the Pro Tools cM sharing tool gives us a better chance of finding the link.
