Dylan Lethbridge-Stewart

Dylan Lethbridge-Stewart was a nephew of Alistair Gordon Lethbridge-Stewart.

In 1970, the Brigadier finally embraced Dylan, the son of an alternative-reality version of Gordon James Lethbridge-Stewart, who was brought to the Brigadier's Earth in 1959, when he was only ten, as a second nephew. (PROSE: Times Squared, Night of the Intelligence)
