[Notarial records concerning Rayer and his family].

Firstly, this paper recalls the way by which Jean Théodoridès, after having worked for many years on Casimir Davaine, had been led up to study the life and works of Pierre Rayer who had been the Davaine's master. Secondly, the author relates how his friendship with J. Théodoridés led him to investigate some new documents and information to complete Théodoridés study on Rayer. At last, he shows that a more systematic search in notarial recordre could give him, later, a better knowledge of some aspects in the private life of Rayer and his family.
