EAST NEW MARKET - Sylvia Maria deJongh Casey, 86, of East New Market, died Wednesday, March 9, 2011, at Chesapeake Woods Center in Cambridge. Sylvia was born on Oct. 27, 1924, in Roanoke Va., the 4th child of the late Georgie Jones deJongh and Peter deJongh. Sylvia, her husband John Casey, and their children lived and worked in Silver Spring, Md., for over twenty-five years.
