a fountain or well, from the old word _doboir_, water. Wells and fountains were held in great veneration by the Celts in heathen times, and are the subjects of many traditions in Ireland and Scotland. Many of the early preachers of Christianity established their foundations near these venerated wells, which were the common resorts of the people whom they had come to convert. In this way the new religion became associated in the minds of the converts with their favourite wells, and obtained the names of the saints, by which they are known to this day; _e.g._ Tobermory (St. Mary’s well), in the Island of Mull; Tobar-na-bhan-thighern (the chieftainess’s well), in Badenoch; Ballintobar (the town of the well), Co. Mayo, now called Tobermore (the great well), which had a well blessed by St. Patrick; Tibbermore or Tippermuir (the great well), in Perthshire; Tobar-nam-buadh, in Skye (the well of virtues); Tipperary, anc. _Tiobrad-Arann_ (the well of the district of Ara); Tipperkevin (St. Kevin’s well); Tipperstown, anc. _Baile-an-tobair_ (the town of the well); Tobercurry (the well of the cauldron); Toberbilly (the well of the old tree); Tobernaclug (the well of the bells, _clog_). Bells were held sacred by the Irish on account of a certain bell favoured by St. Patrick. Perhaps the rivers Tiber and Tiverone, as well as Tivoli, anc. _Tibur_, may come from this root.
