The French

* Henriette Renan, sister of Ernest, "Henriette, twelve years his senior, became the moral head of the household."   "Henriette had accepted in the family of Count Zamoyski an engagement more lucrative than her former place. She exercised the strongest influence over her brother, and her published letters reveal a mind almost equal, a moral nature superior, to his own."   E. Renan's "correspondence with his sister Henriette, (etc). appeared during the last eight years of the 19th century."   (data from the Internet).
