I know this response is probably a little late, but I guess better late than never. To contact the Ifoulds related to Trevor and Peggy Ifould your best option is to contact the directory service for South Australia. Her son Brian has a listed number in McLaren Vale. Peggy is still living in McLaren Vale but any contact would need to be thru one of her kids. Pretty much any Ifould in the Adelaide directory is related to her, but Brian your best bet :)
