The Hoolihan Surname Project
HOOLIHAN, HOULIHAN, O'HOLOHAN, HOLLAHAN, HOLOCHAN, O'UALLACHAIN, HALLAHAN and any other reasonable spelling variations are welcome to join this project. Only males have Y-chromosomes so only a male HOOLIHAN (or variant spellings) can participate. If you are female, you can have a male HOOLIHAN (or variant) relative submit a DNA sample for your line. Hoolihan is a name who spelling varies a lot by generation. Vital records can be limited in Ireland. The Hoolihans (and variants) are a part of the Irish diaspora across the globe, and by participating in this project, there is a chance we might be able to close some of those genealogical gaps and find connections.
