The project has identified three distinct genetic branches of men who state ancestry from County Cork. It is not yet clear which genetic branch emerged from the Cineal Laoghaire branch of the Eoghanacht, though it is likely one of the branches under haplogroup R1b rather than I2.
Among the medieval pedigrees linked below is a claim that west Cork Hurleys are descended from Limerick. Historian Jeremiah O'Mahony generally disagrees, citing the Cineal Laoghaire origin, though perhaps some Limerick Hurleys of non-Cineal Laoghaire origin did drift into Cork.
Besides the name form Murley, the Hurley name was sometimes interchanged with Herlihy in the old records, particularly in northwest Cork.
Medieval Pedigrees at the Hurley project.
The TAB of Shanaway East, Ballymoney in 1833 shows men named Hurley written as Murley. See #59 and #61. The initial letter of the surname looks like the initial M in Manning and Mahony written on the same page. There is a crossbar in the initial H in Healy missing from M in Murley.
The form Murley is not present in the land valuation notebooks prior to Griffith's or Griffith's Valuation itself, at least not in Shanaway East.
This is also recorded under Name Forms at the Hurley project.
