Many genetic genealogy enthusiasts are testing pioneers, having taken Big Y and more. Preliminary work by Alex Williamson (ytree.net) and Nigel McCarthy (McCarthy DNA Study, R-CTS4466Plus DNA) has sketched out an SNP progression CTS4466 (South Irish, Type II), then A1135 (which Alex calls ambiguous), then Z16259. Z16259 has been identified as a potential relevant Uí Fidgenti marker. A1135 includes cousin branches to the Uí Fidgenti.

The goals of the project are as follows:

• Discover the genetic signatures (STR signatures and SNPs) of the rulers of the Uí Fidhgeinte and their ancestors, thereby providing some physical evidence that these semi-mythical people existed.
• Align our results and conclusions with the following haplogroup, tuath, and region DNA projects: Munster Irish, Corca Laidhe, R-L21 South Irish, Eoganacht Septs.
• Discover the genetic signatures of those who may have resided in the tuath, possibly having relocated into adjacent tuaths and into more distant regions, such as West Cork.
• Contribute to the evolution of the relevant surname projects as we discover those surnames belonging to the Uí Fidhgeinte.
