Toberkieraun, in the townland of Ramolin in County Mayo, carries within it the Irish word tobar, meaning a well, and the personal name Ciarán, one of the most widely distributed saints in early Irish Christianity. Wells bearing Ciarán's name appear in several counties, each one a small node in a network of local devotion that predates parish boundaries and, in many cases, the Norman arrival in Ireland altogether.

Holy wells of this type were not simply water sources. They functioned as places of pattern, the local word for a seasonal gathering combining prayer, communal ritual, and sometimes music or trade, typically held on a saint's feast day. The wells were often credited with curative properties, particular to the eye, the skin, or general ailments, and offerings of cloth, coins, or small objects might be left at the site. Many survive in use today in some form, while others have been absorbed quietly into farmland, their physical features reduced to a depression in a field or a clump of vegetation marking a reliable spring. Where Toberkieraun now sits in the landscape of Ramolin, and what physical fabric remains, is not currently documented in available sources.
