Crone Well is a natural spring in an overgrown area, lying just outside an ecclesiastical enclosure and marking one of the headwaters of a small north-south stream. It appears on the Ordnance Survey six-inch maps of both 1839 and 1940, named in gothic lettering on each, which is the typographic convention those maps used to signal places considered ancient or sacred. The well has all the outward markings of a holy well, the kind of site traditionally associated with pilgrimage, pattern days, and the leaving of offerings, yet there is no record of veneration at this one, nor any physical evidence of it.

The scholar John O'Donovan, writing around 1840, recorded the well as being dedicated to the Blessed Virgin Mary. But the name itself, Crone, may point in a different direction entirely. It could derive from St. Brocán of Clauin Iomarchair, a place in Ossory that has never been satisfactorily identified. Brocán appears in a Life of St. Abán, one of the early medieval hagiographical texts that circulated in Ireland, where his role is a minor and rather unflattering one: he is named as the uncle of a thief who stole Abán's pigs. It is a small, odd biographical detail to survive the centuries, and it does little to illuminate why a spring in Wexford might carry his name, or whether it does at all. The connection remains speculative.
