Notes on Project History

Three people with west Cork Hourihane ancestry corresponding with each other wondered about the genetic origins of the Hourihanes and the Y DNA project was thus launched in August 2012.

Because of similarities to other Irish surnames in written historical and genealogical records, and because of known name changes, the Hourihane DNA project became the Joint DNA projects covering Hourihane, Hor(ri)gan, Han(d)rahan, and Horan.

The decision was made in May 2018 to take all results private so as to eliminate any then and future issues with privacy laws. Any detailed STR analysis on our external website is present there because those testers have given their explicit written permission to utilize their genetic data.

The project is now slowly integrating Y SNP analysis with Y STR analysis and documenting its findings on our project website.

Houlihane and Hallahan belong in DIFFERENT projects !

Project Background

This joint project is investigating four major Irish surname categories:

  • O'Hourihan(e), Hourahan, Horahan, and variants.
  • O'Horgan, Harrigan, Horrigan, Organ and variants.
  • O'Hanrahan, Handrahan and variants.
  • O'Horan, Houren and variants.

These names are all believed to have originated in Ireland. In old genealogy records, one name might have been written to look like another. For example, Hourihan has been written as Hanrahan. Some names have been anglicized or otherwise changed over time (e.g., Hourihane to Howard or to Horan, Hanrahan to Henderson, etc.) Houricane could be Hourihane or Hourigan. These examples illustrate the difficulties in reading old records.

Please review the surnames on our project website for more extensive backgrounds.

Background on HOURIHANE

Hourihan(e), Hourahan etc appears to have been historically present largely in County Cork.

It was frequently written as Hanrahan in old west Cork church records.

Occasionally the substitution name Howard makes an appearance. There were a few occurrences in which the name was misheard and written erroneously as Harrington, Harrigan or Horgan - more rarely as Houlihan.

Hourihane may have polygenetic origins. Project members stating Cork ancestry exhibit more than one Y DNA haplogroup.

 

 

 

 

 

 

Background on HORRIGAN, HARRIGAN and HORGAN

Exceptions exist, but most of these surnames in the project do nevertheless show a common Y DNA genetic origin. Their haplogroup had an ancient presence around the Irish Sea (both sides).

Men bearing those names clearly migrated.

Horgan and Horrigan especially became a heavy presence particularly in counties Cork and Kerry. Counties Clare, Limerick, and Tipperary also held a considerable number.

 

 

 

 

 

Background on HANRAHAN

There are multiple Hanrahan septs cited in literature and the project results may reflect this.

The name has had a particularly heavy presence in County Clare.

Hanrahan has also appeared heavily in Limerick and Tipperary.

 

 

 

 

 

 

Background on HORAN

Of all the project surnames, HORAN is probably the most polygenetic, with multiple origins.

The Horan map shows a broader surname distribution in Ireland than the distributions of the other surnames.

Some men named Horan show a very remote relationship to men named Hanrahan.
