The novels have also fleshed out the Brigadier's ancestry, establishing that he comes from a long-standing military family. In the New Adventures novel "The Dying Days" by Lance Parkin, he talks about three ancestors who reached the rank of general. One, William Lethbridge-Stewart, was in the retinue of James VI of Scotland and I of England. The other two fought at Naseby and Waterloo. "The Scales of Injustice" names the latter as Major-General Fergus Lethbridge-Stewart. The Brigadier also says in "The Dying Days" that his father died in World War II, fighting alongside Field-Marshal Montgomery in Africa.
