This Y DNA project is for MEN named Hourihane, Hor(ri)gan, Han(d)rahan, Horan, or a close variation. These are all Irish surnames. (See SURNAMES.) It is not sufficient to have a project-surnamed person in your ancestry. The tester must be a man named Hourihane, Horrigan, Hanrahan or Horan and his direct paternal lineage must be of project-surnamed men.
State in your JOIN request the most recent Y DNA test you ordered - Y37, Y67, Y111, or Big Y. One of these tests is required. Y37 is the minimal, "entry level" test.
If you don't already have a Y DNA test of 37 markers or more, see the FTDNA products page:
If you already have a FTDNA account with a swab submitted, log in to your account before ordering your Y DNA test.
See the FAQ for eligibility details, project policies, tips on setting up your account, etc:
Men with non-eligible surnames will likely need to do substantially more testing beyond Y37 and need to follow the FAQ instructions BEFORE clicking JOIN.
See our DNA and Y testing tutorial if you need help understanding the differences between the male line, female line, and universal lineage types of tests:
