The name Callumkill (formerly Kilcallumkill or Kilcholmkill) suggests a chapel dedicated to St Columba there and local accounts state that nearby was a well into which offerings were dropped. RCAMHS found no trace of the chapel site – could the well have been Tobar na Dabhaich, with the village/chapel site nearby rather than where the Callumkill farm buildings now stand (this well is, I believe, on land farmed by Callumkill).
