From Fr. Walsh's History of the Irish Hierarchy:
Clonebrone in the barony of Granard between Granard and Edgeworthstown. The two Emerias are said to have been placed here in the time of St. Patrick and they are also said to have been the daughters of the unfortunate Milcho who refused to listen to the words of salvation from the lips of St. Patrick because the saint had been his captive. It is also said that at the time of receiving the veil they left the impression of their feet in the stone on which they stood.
