So I ended up with the Abernathy Farm being one of my settlements. Kind of by accident as I didn't know just doing that little quest for them suddenly made the place yours.
Anyway other than adding some turrets (which were needed right away as there as an attack as soon as I placed them down) I really don't plan on doing anything else there. There's just the three living there, the dad, mom and daughter who are all named NPC's (the Abernathy's). I have no intention of adding a radio signal to add more settlers.
My question is, can these guys get killed? I assume that the generic 'Settler' can, but these three are named. My concern is the defense (since I know they get attacked now). Is three turrets enough? Should I care? What happens to the place if all three are killed?
PS - I kind of like the daughter to be honest. Not really cute, but nice to talk to and good VA. Like her story with her parents and late sister. Hate to see something happen to her. Course this isn't Skyrim so I can't just pick some of her melons and marry her.
