Baile fearainn beag is ea Gleann Díomais (Nymphhall) laistigh de bhaile fearainn Dhún Mhór i sráidbhaile Dhún Mhór i mBarúntacht na Gailltíre. Is dócha gur ainmníodh é ó theach mór darbh ainm Nymph Hall, a tógadh in aice leis an áit ina bhfuil an Strand Hotel sa lá atá inniu ann. Clann iomráiteach polaitiúil i bPort Láirge, muintir Aland a thóg é go luath sa 18ú céad. Is díol suntais é an t-ainm go stairiúil chomh maith, os rud é gurb é long suirbhéireachta darbh ainm Nymph, faoin gcaptaen William Doyle sna 1730daí, a tháinig ar bhanc saibhir iascaireachta amach ó chósta Phort Láirge ar a dtugtaí an Nymph Bank. Is dealraitheach gur thug Doyle an t-ainm sin ar an mbanc iascaireachta agus ar an long in onóir dá phátrún Aland.
Ní heol go díreach cad as a tháinig an leagan Gaeilge Gleann Díomais, ach is cosúil gur ainm níos sine é ar an gceantar seo, mar nach bhfuil taifead ar Nymphhall sna taifid go dtí lár na 1700daí. Sa leabhar The Placenames of Decies, níl aon tagairt ag an gCanónach de Paor den leagan Gaeilge, Gleann Díomais. Séard is brí le ‘díomais’ de réir an Duinníneach ná “pride, arrogance…..spite, vindictiveness, malevolence” agus tagairt aige do Sheán an Díomais, an leasainm a bhí ar an dtaoiseach Seán Ó Néill, Tír Eoghain.
Nymphhall (Gleann Díomais) is a small townland within the townland of Dunmore in the village of Dunmore East in the Barony of Gaultier. It was apparently named after a house named Nymph Hall, constructed near the site of the present-day Strand Hotel, in the early 18th century by a prominent Waterford political family, the Alands. The name has historical interest since it was a survey ship named the Nymph, under captain William Doyle in the 1730s, that discovered a rich fishing bank off the Waterford Coast called the Nymph Bank. It is likely that Doyle named it and his ship after the Hall of his patron Aland.
The Irish version, Gleann Díomais remains a puzzle, but would appear to be the older name for this area (Glandemus), with Nymphall only appearing in the records from the mid 1700s. In The Placenames of Decies, Canon Power simply says that “Under the head of Dunmore is to be included Nymph Hall, a portion of Dunmore cut off to form a separate townland with the foregoing fancy name” and he gives no Irish version. Dineen gives ‘díomas’ as meaning pride, spite, vindictiveness and arrogance.
