Comhfheagras a bhaineas le Bellfield 2008:

The name Bellfield is derived from a house of this name which was built probably in the late 18th century by the Lett family (see Houses of Wexford p.239). It is probably a compound of the French word belle "pretty" and the English word field. This type of name was common in Ireland during the era of the construction of the 'big-houses', e.g. Belview, Belfield in Dublin, Belpark etc. However, it is also possible that the first element of Bellfield refers to the surname Bell, or indeed it could theoretically be a translation of Gort an Chloigín "field of the bell" or similar. Given this uncertainty about the origin of the name, it is felt that an accurate translation of it is not possible, and therefore Bellfield is the form recommended in the case of an Irish address such as: S. Ó Murchú, Bellfield, Inis Córthaidh, Co. Loch Garman.
