Dear Listers, Jack Hayes COCK/S was b 2nd January 1910, the twin brother of George Dudley COCK/S, at Rose Park Adelaide. It is believed that Jack moved to Queensland during the 1930's and remained there for the rest of his life. Is anybody researching this family or know anything of Jack Hayes COCK/S. ANY assistance would be very much appreciated. Regards, Stephanie Cocks, Adelaide.
