An English and Scots patronymic, ‘son of Robin’ — a Plantation-era settler name across Ulster.
Scottish/English Origin · Root meaning ‘son of Robert’
Robinson is a patronymic built on Robin, a familiar form of Robert, and arrived in Ireland as a settler surname during the Plantation period rather than through any Gaelic line.
No sept, no translation, no older story to tell — just a name that put down roots in Ulster and stayed exactly as long as anyone else's.
