Welcome to the DNA Project website of Hourihane, Hor(ri)gan, Han(d)rahan, and Horan, which was created in August 2012 to support the O'Hourihane DNA Projects. The project aggregates Y-DNA tests of participants and analyzes them for both very recent genealogical relationships and deeper haplogroup relationships. Y-DNA test takers must be in the direct paternal line of descent from a male ancestor with a surname of interest.

Houlihane/Hoolihane/Whoolihane does not qualify.

Were the O'Hourihanes erenaghs of Ross? Did they come from County Clare? Was the name ever anglicized as Horan? Were they secretly Horgans? Or were they Hanrahans who migrated down from Tipperary? Visit the Project Background and Project Goals pages for more details on what we aim to cover. There are many surnames to examine, not just O'Hourihane. See the sample surname distribution map below. Specifically, we want to differentiate between the Galway-based O'Horan group, the Tipperary-based O'Hanrahan group, and Cork-based O'Horgan, where such distinctions exist. Variants for these three surname groups have been confused for each other. The areas of geographic interest are Cork, Kerry, Tipperary, Limerick, and Galway, but may spread to other counties. A major goal of this project is to bring some DNA clarity to these names.

If you do not join the DNA project but otherwise wish to be notified of project activities and DNA test sales, mailing list membership (above ^^^) is required.

DNA Project

Men with a surname of interest who have taken a Y-DNA test are eligible to join. Any man or woman with a surname of interest in any line of their ancestry (not just the direct paternal line) may join with an A-DNA (autosomal DNA) test.
