She [topic-は] this village [genitive-の] everyone [by-から] was-doted-on.
かわいがる ('to dote on, treat with affection') is the verb for showing tender care toward someone — children, pets, juniors, anyone you'd treat with cherishing warmth. The passive かわいがられる ('be doted on, be treated with affection') with から marking the agent of the affection is a classic structure for talking about being on the receiving end of community fondness. みんなから ('from everyone') makes the affection collective — the whole village, not just one or two people. ~ていました locks the affection as a sustained, characteristic state over time. A warm, evocative sentence with a tinge of nostalgia.
