William Lethbridge-Stewart

William Lethbridge-Stewart was a member of the Lethbridge-Stewart family, a part of the Scottish Clan Stewart (DW: Terror of the Zygons). He was therefore related to the Stuart kings of Scotland and, subsequently, England as well as being a distant ancestor of Brigadier Alistair Gordon Lethbridge-Stewart and Kadiatu Lethbridge-Stewart.

A close advisor of King James I in the early 17th century. When the King arrived in London to claim the English throne, Lethbridge-Stewart accompanied him. (MA: The Dying Days)
