134Joan Revington, the lead OPW guide on the Hill of Tara, in a private email message on 21 March, 2019 wrote, "On the first edition ordnance survey map (1836 O’Donovan) and on Petrie’s map 1839 this well is marked as Nemnach, However in Conor Newman’s publication "Tara, an archaeological  Survey" (1997) he identifies the well as Liaig (page 89) and writes that Nemnach is at the southern end of the Hill, at the bottom of the field below Rath Lóegaire (page 47). That’s the interpretation we go with today."
