Thomas* has suggested that mist forming over warm springs might be responsible for the sightings of the Ladi Wen "White Lady" ghost entrenched in Welsh well folklore. That such mists occur is comfirmed by Jones* who gives two wells where this can be seen (Ffynnon Elan, near Gelli'r Pentref Dolwyddelan; Ffynnon Lygaid, Llanfynydd Bog, Carm. which can generate a column of mist 15ft (~4.1m) high) and, indeed, notes (p.126) that a "Lady in Grey" is associated with Taff's Well, near Cardiff, which is known to be warm. However, it should be generally noted that the Ladi Wen association with wells can't be used to mark out warm wells in Wales as the name is also used in association with the "virgin Mary"*(p.45/126), presumably taking up the "Pure; Sacred" sense of Gwen noted by Bromwich and Evans* (note 159).
