Jonathan Maxson is the father of Arthur Maxson and husband of Jessica Maxson.
Jonathan is not only a descendant of Roger Maxson, the founder of the Brotherhood of Steel, but he was also a high-ranking Paladin just outside New California Republic. He was, however, killed in battle. He and his wife died when their son was still very young, making Arthur the last of the Maxson bloodline by 2277.
- Fallout 3 Official Game Guide Game of the Year Edition p.98: "Squire Arthur Maxson
Squire Maxson is a descendant of the legendary Roger Maxson, founder of the Brotherhood of Steel. His father, a high-ranking Paladin serving just outside the N.C.R. (New California Republic), was recently killed in battle, and his mother, the Lady Maxson, sent the boy east to be raised under the tutelage of the respected Elder Lyons. Squire Maxson tends toward timidity, which is the main reason his mother sent him to the Citadel."
