All she really knew about Devon was that a large portion of it was a Resistance stronghold. The Weasleys were from the area. It was no secret that because of their family, many of those who wanted to tear down the current government set up stakes near their family home. Arthur refused to join in with the traitorous activities. His reluctance to aid his three children active in open rebellion against the Dark Lord was well-known. He didn't even speak to Charlie or Percy or his only daughter. It saddened Hermione that he couldn't even have the comfort of his surviving children all being together because several of them were so dead-set on watching the world burn around them. If Molly had survived, she would've been horrified how they abandoned their father. Or, she would've been the spark Arthur needed to keep up the fight.
