Origin of name: The road takes its name from Aughnabrack House, a historic dwelling in the area.
Historical reference: Aughnabrack House is shown on the OSNI Historical Second Edition (1838–1862) map, confirming the presence and significance of the property during the mid-19th century.
Notes: The name "Aughnabrack" is likely derived from the Irish Achadh na Breac, meaning “field of the speckled ones,” though exact origins may vary.
