Viscount of Oxfuird

He had already been created a baronet, of Makgill, in the Baronetage of Nova Scotia on 19 July 1625, with remainder to heirs male whatsoever.

Her son Robert Maitland Makgill also voted as Viscount of Oxfuird at the election of Scottish representative peer in 1733.

His younger son George Makgill, the de jure seventh Viscount, fought in the Jacobite army of Bonnie Prince Charles, was attainted but later pardoned.

His great-grandson John Makgill, the de jure tenth Viscount, resumed the claim to the Baronetcy, Lordship and Viscountcy.

Shortly after his death in 1906 the matter was resolved in his favour in regard to the Baronetcy, but the Lordship and Viscountcy still remained dormant.

The Viscounts' seat was the original Oxenfoord Castle in Midlothian, built by the MakGills in the 16th century.
