John Sedgwick
Edgar was not able to make up his mind to marry, until 1882. Edgar's wife, the Berlin-born Katharina Wilhelmina Heine (1859–1945), was the daughter of american lieutenant colonel Wilhelm Heine and his spouse Katherine Whetton Sedgwick (Albany/N.Y.1824-Berlin 1859) and related to Civil War (1861-1865) general John Sedgwick (1813-1864).
