The proposed flag for Wigtownshire is taken from the arms
used by the former Wigtownshire County Council, where the design appears as a “chief”, the top section of the shield. This in turn was based upon the arms of the Dalrymple lords of Stair
who owned significant territory in the county, with the colours reversed
as found in the badge of the local Stranraer Academy
