DNA Research


The male Y chromosone contained in a DNA sample is passed down the male line virtually intact. Thus, if two male DNAs closely match then it can be scientifically proven that these people are related. This is explained more at www.familytreeDNA.com.

I have set up a Hayde research project as part of this study. Click here to be directed to this site.

This shows that:

  • The DNAs reflect three broad sets of data,
  • One set of data relates to the German connection mentioned above,
  • The other two sets have Irish origins.

One of the Irish sets is from Haplogroup (origin) R-M343. This is a very common Haplogroup in Central Europe, Spain, France, Portugal and the British Isles. Sub groups include R-L48, R-U106 and R-P312, the three groups featured in the Hayde/Hade results.

Similar to the Haplogroup R-M343 are the results from R-M269. This Haplogroup is the dominant lineage in all of Western Europe today.

These two sets of groups seem to have Norman origins and I have labelled this grouping as of ‘Norman Origin’ on the web site. This is very conceptual at present and the haplogroups are going through continuous further testing. What is interesting is that the Haydes in this group have very similar DNAs to families that have origins in Lancashire.

The other Irish set is from Haplogroup I-M223. This Haplogroup has Scandanavian origins. I have labelled this group as of ‘Viking Origin’ in this data. There is also a group studying this origin in more detail and as the research progresses these origins will become clearer.

Both the two Irish DNA sets can all be traced back to County Tipperary. An area that I suspect is around Ballingarry. As the sets come from the same location, I assume a NPE (non paternal event) occured at some stage that introduced the other DNAs.
