Wikipedia states that Louis (born 1872) was one of the founders of La Vérité française, a secret newspaper of the Resistance which brought out thirty-two issues before they were arrested. At seventy-one, he was apparently beaten to death by a Polish inmate in 1843 in Sonnenburg prison. The page also notes that Marie-Louise died in Bergen-Belsen in 1945.
