DNA Results Analysis and Information on Irish Origins for the Rock Surname

What have the DNA results so far revealed? - Some Great Successes

Aside from the personal matches revealed for each individual, there are seven members who all appear to be related. This is a personal success for these people and shows how in the absence of paper trails DNA can achieve success. Reuniting a once close knit clan, from now scattered communities, a;; sharing the same surname. The most dramatic appears to be member John Joseph Barrett who matches the Rocks of Armagh. Indeed he believes his existing surname is not his correct genealogy and the DNA results show this to be the case. Not only that it has opened a closed door on his personal history, it has closed another.

Important point to Consider:
Your haplotype, (your personal set of DYS marker results), determines the amount and type of DNA matches to other surnames. For instance, both Rock testers, Kit Numbers 45758 and 33409 are determined by FTDNA as a Western Atlantic Modal haplotype (WAMH). Both these have a very broad and sporadic set of surname matches, there is nothing conclusive at all in their surname matches. Kit number 32714 is R1b1c3 and has a lot of very specific different surname matches - all historically inter-related and from the same location. So its your haplotype that is more critical not your Haplogroup.
