William DeWolf Hopper b. 30 Mar 1858, d. 23 Sep 1935 in Kansas City, MO. His parents were John Hopper and Rosalie DeWolf. The book "Mount Hope, A New England Chronicle", by George Howe, Viking Press, 1959, a family narrative of interest, mentions him and says of him "To know him was to marry him," as he was married 7 times. Among his wives (i only have three) were his cousin Nellie DeWolf Gardner, Ellenor Bergen and Hedda, the gossip columnist, by whom he son William deWolf Hopper, Jr, who played the detective on Perry Mason. I do not beleive any connection to Dennis Hopper.
