Lethbridge-Stewart family

The Lethbridge-Stewart family was a storied one. Notable members included Alistair Gordon Lethbridge-Stewart.

Origins
Originally the Lethbridges were from Devon, and went on to be the Lethbridge Baronets of Devonshire, while in Lanark, Scotland, the Stewarts were part of the Clan Stewart (PROSE: The Forgotten Son) and related to the Stuart kings of Scotland. When James VI arrived to claim the English throne as James I in 1603, the Brigadier's ancestor, William Lethbridge-Stewart, accompanied him. (TV: Terror of the Zygons, PROSE: The Dying Days)
