According to what national personification, would land's named or derived from "Erin" have a feminine personification?
Erin Erin is a Hiberno-English derivative of the Irish word ""Éirinn"". "Éirinn" is the dative case of the Irish word for Ireland - "Éire", genitive "Éireann", the dative being used in prepositional phrases such as ""go hÉirinn"" "to Ireland", ""in Éirinn"" "in Ireland", ""ó Éirinn"" "from Ireland". The dative has replaced the nominative in a few regional Irish dialects (particularly Galway-Connamara and Waterford). Poets and nineteenth-century Irish nationalists used "Erin" in English as a romantic name for Ireland. Often, "Erin's Isle" was used. In this context, along with Hibernia, Erin is the name given to the female personification of Ireland, but the name was rarely used as a given name, probably because no saints, queens, or literary figures were ever called Erin.
Órlaith Órlaith (older spelling: Órfhlaith, newer spelling: Órla) is an Irish language female given name. Orlagh is a hybrid spelling based on a merger with another suffix. The meaning of the name dervies from Ór, meaning "Golden" and Flaith, meaning "prince" although as names with "flaith" suffixes are almost always exclusively feminine, this is usually interpreted as meaning "princess". The retention of the 'fh' within the spelling maintains the ability to easily derive the true meaning of the name, but as this is silent, it is common to see this redacted. All spellings of the name are however pronounced the same, as "OR-la".
