Hello Alison, Re your posting concerning members of the Briggs family. There was a C H BRIGGS living at 51 Lake Avenue, Killarney Vale in Wyong Shire listed in the 1971 Gosford telephone directory. Also an I H Briggs living at Trelawney St, Killarney Vale. Try the Probate Index for C H Briggs, seeing he was born in 1894. And have you checked the current NSW Electoral Roll for younger members of this family? Not much help, but a little something. Best wishes, Gwen
