Sources differ on the names of the three saints, with some naming St. Laitiaran as one of the trio. According to the Diocese of Kerry, "This veneration extends to the modern parishes of Rathmore/Knocknagree, Milllstreet/Cullen, Dromtariffe and Ballydesmond. We don't get agreement on the names of her two sister saints in the tradition. Most usually Latiaran of Cullen and Crobhdhearg are found in the tradition but sometimes a saint called Iníon Buí is substituted for either Latiaran or Crobhdhearg." ("St Gobnait." Diocese of Kerry. Web. 12 Nov. 2012. <http://www.dioceseofkerry.ie/page/heritage/saints/st_gobnait/>.)
Frank Coyne notes that "It is significant that three female saints have holy wells, almost equidistant from each other, and have their feast days on three of the quarterly feasts of the old Irish year, with a site referring to the Cailleach perhaps representing Samhain, as a completion of the annual cycle." (Coyne, Frank. Islands in the Clouds: An Upland Archaeological Study on Mount Brandon and The Paps, County Kerry. Tralee, Co.

Information on the Mórrígan may be found here. There may be an echo of the Mórrígan story in this tale, included by Dan Cronin in his book, as told to him by Own McCarthy: "Long ago there dwelt a beautiful maiden in a famous sidhe, Bergh Elda. On the Eve of Samhain, when nothing could be hidden in the sidhe forts, many of the men of Erin sought her hand in marriage. But the only reward that each one got for his trouble was that one of his party was killed, by whom or what could not be ascertained. However, when a friend to Fionn went to court the maiden and met with a like fate, Fionn sought counsel from an acknowledged champion, Fiacail Mac Conchinn, who advised him to go and take up a position between the two mountain peaks known as the Paps of Dana. While seated there on the side of the little pathway, to this day known as Bóthar á Chích, on Sarnhain Eve, Fionn saw two large mounds that were between the Paps, one on either side of Bóthar á Chích, open, disclosing a huge fire burning inside each of the mounds. Then he heard a general interchange of sounds and commotion being conducted between the mounds. A man emerged from one of the liosanna and he went in the direction of the other. He carried a wooden container, laden with food and some greenery. Fionn poised himself and threw a spear at the apparition. Immediately he heard loud weeping and keening in the rath from which the man had emerged. It has been claimed that Fionn's victim was the destroyer of the suitors followers." (Cronin, Dan. In the Shadow of the Paps. Killarney: Crede, Sliabh Luachra Heritage Group, 2001. 24-5.)
