I have no other info and no other source of info' So am at a dead end for the moment I'll keep the Victorian, South Aust and Yorkshire message boards posted for any one who can provide a possible addition.
I might try to source the correctYorkshire/Malton Birth cert for John Young but there about 3 possibles. Maybe someone who can sight them before buying.
Well done Rhonda for all the Docherty data. Bye for now Ron
