Marie-Cessette
was the name of the grandmother of Alexandre Dumas. She was a slave
owned by Marquis Alexandre-Antoine Davy de la Pailleterie (Dumas’s
grandfather) and lived on a plantation in the colony of
Saint-Domingue (Haiti). In “The Black Count“ by Tom Reiss it is
stated that it is not clear if she was a black woman or of mixed
race. Either way we already know that the role of Porthos is meant to
be as a homage to the parentage of the author of “The Three
Musketeers“. In the first episode of season three Porthos says that
he “[…] was named after [his] mother’s father“. I really like
the idea to let him name “his“ daughter after “his“
grandmother.
