Jeanne Roques, aka Musidora

I'm an American author researching the life and career of the french silent film actress/director/writer Musidora, who was born Jeanne Roques on February 23, 1889 in Paris. She died on December 11, 1957, also in Paris. She married Dr. Clement Marot in 1927 and had one son, Clement Jr (birthdate unknown).

I'm trying to track down any information about her family and especially locate any living descendants.
Any assistance would be greatly appreciated.
Thanks,
Laura
