Maigh Bhachla
Logainm — the State place-names database — gives the village as Maigh Bhachla, the plain of the crozier. The bachall is an abbot's or a bishop's staff, and Irish place-names that carry one usually carry a saint or a foundation with it: a relic, a pilgrim route, a hermitage long since gone back into the field. The specific story behind Moyvoughly's crozier has not survived in any source you can verify in a session at a desk. The name has, which is the way of these things — the saints went, the staves went, the syllables stayed. The older English spelling was Moyvaghly; the current form Moyvoughly is a nineteenth-century smoothing.
