Wellborn → It is formed from "well" (from Old English *wel*, meaning in a good or satisfactory manner) and "born" (from Old English *boren*, meaning to be born). The word "wellborn" refers to someone who is born into a good or noble family.
Think of someone who is 'born' ('boren') into a 'good' ('wel') family — that's why 'wellborn' means having noble or good origins.
