'A concise history of Port Beaufort & White Sands (also known as Witsand) including Family Trees White Sands & Port Beaufort' by John McGregor.

The Moodie Book - http://archive.org/stream/moodiebookbeinga00ruvi#page/n49/mode/2up (pp. 11-14)

On p. 11: "William Mudie of Breckness, near Stromness, in the Mainland of Orkney, and of Snelsetter Castle and Melsetter, in Walls; Chamberlain of Orkney under Queen Mary, probably eldest son and heir of the preceeding [ie Gilbert], with whom the pedigree ceases to be conjectural".

William's parents, Gilbert and Elizabeth, are said to have married 'before 20 January 1544' but there is no indication (in the Moodie book) of a date of birth for William.

Mentioned in Charters dated 1563, 1564, 1565. Appointed Rector of South Ronaldshay and Burray November 1570; transferred to Hoy and Graemsay before 1574; and to Walls and Flotta between 1580 and 1585 (he took a gift of the patronage from Queen Mary). Mentioned in Charters dated 1589 and 1591, the latter confirming to him and his wife the lands of Melsetter, Snelsetter and others.

William Mudie died between 20 November 1595 and 30 June 1597.
