The house and its townland share a name that derives from the Irish "lorgain", meaning a long, low ridge of land, a quietly descriptive placename of the sort that tends to outlast whatever buildings have come and gone above it.

Without further detail in the surviving record, the house resists easy categorisation. County Galway has no shortage of country houses that passed through cycles of construction, inheritance, decline, and ruin over the eighteenth and nineteenth centuries, many of them associated with the landed families who held estates across Connacht during the period of English and Anglo-Irish settlement. Whether Lurgan House belongs to that pattern, or represents something older or more modest, is not possible to say with confidence from what currently survives.
