Hi Anne. I will attach a list of notes I have made concerning my mother's side of the Dorizac family. CF (grandfather) Dorizac had seven children. Nelson, the father of Les was a piano tuner and we suspect a porter of Dupuytren's disease that one other male cousin and I have suffered from. Les was an entrepreneur and married a Chinese national, imported pianos from China and had some branded in his name. He was also a record distributor and I will always grateful to him passing me the first Bob Dylan record as well as a French recording of Irma la Douce. My sister and I believe my grandmother, Irma Dorizac, was in fact the daughter of her older sister, Eleanor Elizabeth Elvira, born out of town and more or less brought up by the threesome of grandparents and mother. There are very few male Dorizacs still standing. As far as I know only Raymond , Les's brother, has a son Owen Dorizac b 1950. All the other lines appear to have been shy breeders or drowned in female offspring.
I would be happy to share my documents with you if we can make contact. I live in Pezenas.
