His youngest son Charles Eugène Gabriel de Sombreuil was one of the commanders of an emigre counter-revolutionary force that made an abortive landing at Quibero in 1795. Charles was amongst 750 royalists prisoners subsequently executed by firing squad on 28 July, at the orders of Lazare Hoche. Mademoiselle de Sombreuil eventually married in 1796, and died in May 1823.
