MacDowell / Dowell	McDowell / McDowall

The name McDowell or MacDowall in Ireland is derived from the native Gaelic Mac Dubhghaill Sept that was located in County Roscommon and is the Irish form of the Scottish MacDugall name. Other descendants bearing the name derive from the many immigrants who arrived into Ulster in the seventeenth century. The name translates from Gaelic as 'dark foreigner'.
