Folklore collected in 1937 from Currach Beag (Coarha Beg) School recorded the following tradition; 'Ballymanagh or Monkstown is situated on the eastern side of the island. This townland is very rich. This is how it got its name. "St. Patrick" had a niece named Dairerca. He sent her to this Island because he thought that the pagans would do her a disservice. She established a monastery there in this domain. It had a lot of monks in it and from then on it was called "Baile Mánach". There is now a blessed well where the monastery once stood' (The Schools’ Collection, Volume 0479, Page 011;https://www.duchas.ie/en/cbes/4742141/4740136/4815525?ChapterID=4742141).
In 1938 the following folklore was collected from Baile and Ridire or Knightstown School; 'St. Dererca's well is also called "Tubbereendoney" or "Tobar Rí an Domhnaig". St. Derercas was a sister to St. Patrick. She came with a number of nuns to Valentia and they had a convent in Ballymanagh. The well in which the nuns used get the water is called "St Dererca's well". Formerly a "pattern" used to held at this well; but at that time intoxicating drinks were very cheap and several people were drunk at the pattern. The priests then ordered the pattern to be discontinued' (The Schools’ Collection, Volume 0479, Pages 066-7; https://www.duchas.ie/en/cbes/4742142/4740193).
