Yes, I remember as a small child once being taken to the office of 'Uncle Doc' who was actually not a doctor, he was a dentist who worked in San Francisco. The nickname of 'Doc' is evocative of a certain era of which I know almost nothing. He was, however, my uncle in that he was married to my mother's sister. However, they later divorced and I do not know enough about Doc to stick in your eye. Needless to say.
