McCarthy Surname Study

About us

The McCarthy Surname Project is testing for mutations on the Y-chromosome which:

(a)        
take research of paternal lines beyond the limits of conventional genealogy, and in so doing, identify their origins.
(b)        identify shared paternal ancestry.

(c)        distinguish McCarthys (and variants of the name) from one another, and from those of other surnames.
(d)        establish Y-DNA profiles associated with the various M(a)cCarthy septs, subsepts and agnomina.
(e)       
confirm or refute suspected or claimed origins.
(f)         test the veracity of both ancient and more recent written genealogies.
