Gendreau — spelled variously as Gendrou, Jaundro, and Jondrieux in the records — was a member of the Second Relief. François Gendreau, a Canadian employee of Sutter’s, is mentioned several times in the New Helvetia Diary. His wife was a Walla Walla Indian; one of their children was buried at the San Jose Mission in 1844. Bancroft was uncertain whether it was François or his son who went to the rescue, but the Donner relief documents make it clear that it was the son, Joseph.
