Pauline, I believe that 2 Adelpha Street is actually 2 Adelphi Street. It is located between Flushing Avenue and the Brooklyn Queens Expressway. Number 2 would be right off Flushing Avenue. What was the name of your grandfather's brother who mentioned 358 Canterbries Avenue, Brooklyn? Canterbries may well be Canterburys, Centerprize or some other similar spelling. Earle Smith
