During the Fallout 3 mission "The Dark Heart of Blackhall" you meet a missionary who claims to be part of a group called the Abbey of the Road.

http://fallout.wikia.com/wiki/Marcella

Marcella is a nomadic missionary, spreading the word of her own faith. She's come to Point Lookout from a place called "The Commonwealth" aboard Tobar's ferry. Taking the Tribal Cultists and local inbreds for lost causes, she ministers to those she can. She was immediately suspicious of Obadiah upon meeting him and has made a mission of investigating Blackhall's connection to the heathen creed of the Swampfolk.

Could we see the Abbey of the Road in Fallout 4? It's located in the Commonwealth after all.
