About us

Our original mission was to research the HOURIHANE surname and to see - despite its resemblance to the surnames HANRAHAN, HORRIGAN, and HORAN - if it is genetically distinct from the others. Thus, the project examines all these surnames.

The primary goal of the project is to help members find out where their paternal line great*-grandfather was and where he was originally from. Our means of doing this is through finding genetic matches through yDNA. We are carving out distinct genetic groups as a result.

Our secondary goal is the exploration of the deeper origins of Irish men with these surnames in the context of Irish history. Our means of doing this is to keep abreast of the relevant haplogroup research that can shed light on the origins of Hourihanes, Horrigans, Hanrahans, and Horans.

We are trying to achieve our goals with several smaller ones:

  • Assist project members with family history / genealogy records and research, when possible, thereby helping them to identify their ancestry and fill in their family trees.
  • Create a rich DNA database by recruiting new members. In particular, target testing candidates who can prove ancestry back to a specific location in Ireland (i.e., candidates with "high value" genealogies). This will further help members who have not identified the origins of their paternal ancestors.
  • Identify and carve out relatively recent genealogical groupings, assigning a terminal haplogroup/SNP label to each.
  • Contribute to deep SNP research, and thereby the evolution of haplogroup research, by encouraging SNP testing, once members have done sufficient STR marker testing.
  • Review literature on the origins of these surname(s), along with state of the art haplogroup discoveries, to determine whether correlations can be made between any origin hypotheses and haplogroups.
