Charlie with sister-in-law, Minnie, on the set of CITY LIGHTS, c. 1930

Minnie Gilbert Chaplin, a former Fred Karno Company performer, was the first wife of Charlie's half-brother, Sydney (although there is no legal record of their marriage). She appeared in five of Sydney's Keystone films and makes a brief appearance in one of the dancehall scenes in A Dog's Life. She died of cancer in 1936.
