What is "whithorn"

Whithorn (Taigh Mhàrtainn in Gaelic) is a former royal burgh in Dumfries and Galloway, Scotland, about ten miles south of Wigtown. The town was the location of the first recorded Christian church in Scotland, Candida Casa : the 'White [or 'Shining'] House', built by Saint Ninian about 397.

Whithorn in Wigtownshire was a royal burgh that returned one commissioner to the Parliament of Scotland and to the Convention of Estates.

After the Acts of Union 1707, Whithorn, New Galloway, Stranraer and Wigtown formed the Wigtown district of burghs, returning one member between them to the House of Commons of Great Britain.
