McDowell is a Scottish and Irish surname whose history links Galloway, the western isles and Ulster.
Where does the McDowell name come from?
McDowell is an anglicised form of Gaelic Mac Dubhghaill, “son of Dubhghall.” The personal name is commonly interpreted as “dark stranger,” a term used in Gaelic tradition for darker-haired Norse settlers. McDowell shares this Gaelic origin with Scottish McDowall and McDougall, but the modern spellings should not be treated as interchangeable without supporting family records.
McDowell in Ireland
Some Mac Dubhghaill families came from the western isles as gallowglass soldiers during the later medieval period, and a number settled in Roscommon. Many Ulster McDowells descend from Scottish settlers who arrived later. By the nineteenth century the surname was numerous across Ulster and also recorded in the Louth–Meath area.
