Welcome to the Scrapbook pages for the McCarthy Surname Study, which analyses the Y-DNA of men named McCarthy or a spelling variant or agnomen associated with this name. The files made available below support the main Study website at: https://www.familytreedna.com/groups/mccarthy-surname-study/about

Y-DNA Phylogenetic Trees

Note: most trees were temporarily removed on 21 May 2018 pending verification that kit ‘Owners’ had sanctioned display of all their Y-DNA data in the public viewing of FTDNA’s DNA Results charts along with use of other data available used for their construction. They are being reinstalled one by one as and when appropriate checks, with complete anonymisation of identities where not so sanctioned, have been completed.
