The Gardner name has a long history in British Isles, but now DNA and some recorded history says their origin is from the Emerald Island. The Gardner story [dominated by DNA tribal marker R1b-L513, Subgroup B2] can trace their origins to the Finn Valley in Donegal, Ireland from 50 BCE. Perhaps the journey begins with the Clanna Dedad; Deda, son of Sen or Deda Mac Sin. The Gardner surname origin is from Clan Domnaill [DNA Tribe R1b-L513, Subgroup B1] and relations who remain in Ireland take the modern surname (O’)Donnelly, McDonald and Donohue in Ireland.
