Robert D'Unger was my great grandfather. His father was Henri D'Unger who ran a mill near Hagerstown, Maryland and later moved to Pennsylvania. His mother was Sarah Speer of Pennsylvania. His second wife, my great grandmother was Laura Keene of Dorchester County, MD. Sarah Speer was the daughter of Robert Speer and Elizabeth Gailbreath of Pennsylvania. My grandfather, his first son, was Claude Vachel D'Unger who was born in Maryland. Dr. D'Unger was both a physician and a newspaper publisher. He moved from Maryland after teh Civil War to Duluth, Minnissota and later to Chicago where he had an office in the Palmer Hotel for many years. I can give you more information if you are interested.
