EDAENA.  "Perfect happiness" or "rich gift."  Swan derives this name, and its variant Edana (q.v.) from Old English ead, signifying "happiness" or "riches."

    An Irish St. Edana or Edaena is the titular Saint of New Tuamia, and a famous holy well much resorted to by the sick, bears her name. (Girls' Christian Names, Swan, 1905).
