I can't restrain myself, I have to show off: today for the Freeman book I drew this conception of the Keen family shortly after the death of the doctor's wife, Emma Corinna (usually called Tinnie). On Dr. Keen's right is his daughter Florence, who never married and who lived with her father until his death, keeping house for him; on his left eldest daughter Corinne, about eighteen and not yet the mother of Walter, holds hands with her little sister Dora. There was actually a fourth daughter, the youngest of all, Margaret, but I left her out for my own nefarious reasons.
Margaret was the second to marry, after Corinne; she became Margaret Keen Butcher. Dora was single and lived with Dr. Keen and Florence until she was in her forties, when she married a German she had met on the side of an Alp and became Dora Keen Handy. You can look these names up yourself if you don't believe me.
