Tobar na Saighead appears on Ordnance Survey maps from as early as 1841 to 1842, and again on the 1914 edition, each time recorded under its anglicised form Tobernaseeth. Whatever the arrows referred to, whether a battle, a legend, or some feature of the local landscape long since forgotten, the knowledge has not survived.

Holy wells and named springs were once densely threaded through the Irish countryside, many of them focal points for seasonal rounds, small offerings, and accumulated local lore. Tobernaseeth retains the form of that tradition without any of its content. The well lies in a large field beside Kissane's house in Tullahennel, but it has been covered over by a concrete building, and the water it once held now serves rather more practical purposes, piped for domestic use and made available to cattle. No pattern day is recorded, no rounds are associated with it, and no legend, however fragmentary, appears to have been passed down. The name is essentially all that remains, and even that name is now an open question rather than an answer.
