Dumbartonshire

Dunbartonshire (Scottish Gaelic: Siorrachd Dhùn Breatann) or the County of Dumbarton is a historic county, lieutenancy area and registration county in the west central Lowlands of Scotland lying to the north of the River Clyde. Dunbartonshire borders Perthshire to the north, Stirlingshire to the east, Lanarkshire and Renfrewshire to the south, and Argyllshire to the west.
The county covered a similar area to the earldom and later duchy of Lennox. The historic county gives its name to two of Scotland's modern council areas, being East Dunbartonshire and West Dunbartonshire.
