For all of these profiles - it takes more than just DNA
It takes careful study of documentation as well first - then the FTDNA years of study -

I would want to see the documentation to back up any changes first.

I know for the Harris lineage they have careful paper documentation along the way first - then the FTDNA y-DNA
