As far as official D&D canon goes, Abdel Adrian was the protagonist of the Baldur's Gate novels. In terms of gaming material from the tabletop, Baldur's Gate (and Neverwinter) pretty much disappeared from the continuity in 1368DR and only returned for 5e over a century later. They existed on the map, but if there had been an earthquake or mystic atom bomb, the fishing village just up the coast wouldn't have felt it. From what I could dig up in BG3, the name didn't stick out while I was playing, although I'd probably have to revisit a certain crypt to be sure.
