A Magazine Article About Daphne du Maurier and her French Ancestors
The June edition of the magazine La Vie Mancelle & Sarthoise includes a four-page article, with a number of photographs, about Daphne du Maurier and her French ancestors. The article, written by Bernard Hinault, is called Du Château des Rêves au lieu-dit des réalités, which translates into English as From the Castle of Dreams to the Place of Realities. It describes the long search, from 1955 to 1961, that Daphne undertook to find out about her French ancestors.
