Doris Lethbridge-Stewart
Doris Lethbridge-Stewart was the second wife of Alistair Gordon Lethbridge-Stewart.
They first met at Brighton in the mid-1960s and had a brief but passionate romance which ended amicably when Alistair was sent overseas. Their relationship seems to have been sexual. (DW: Planet of the Spiders, DWM: The Warkeeper's Crown)
She married, but her husband George Wilson was killed in Northern Ireland. (MA: The Scales of Injustice)
In the 1990s, the Brigadier met Doris again and eventually married her. (DW: Battlefield, DWM: A Romantic Evening) They lived in a large house in the country. (DW: Battlefield)
During a boat outing in the 2010s, the Lethbridge-Stewarts' boat capsized and Doris drowned. (EDA: The Shadows of Avalon)
A conflicting account shows Doris having Christmas dinner with the Brigadier and the Eighth Doctor in 2017. (ST: Not in My Back Yard)
