I've been in contact with Robyn Boughen, She has given me some information. Are you in contact with her.
I received the marriage certificate for Reginald Harry Manners and Hazel Shirley Cortes. They married 25 March 1950 at St Mary's Church, Rydalmere, NSW. Hazel or Shirley as we all know her, was living at Park Road Rydlemere at the time of marriage. She was born in Dalby, Queensland about 1933. She was aged 17 when she married. Her father is listed as Charles Noel Cortes and mother Mary McKeon (deceased at time of Shirle's marriage). Reg and Shirley divorced 3 November 1960.
From what I can work out Charles Cortes' parents were Lorenso Cortes (born 1911 Queensland) and ? Regis, who is believed to have been born in America. Lorenso had a sister named Myrtle(born 1914 Queensland) married Clarence Phillip Mengal 1934 Queensland, and Lorenso's brother Joseph born 1908 Queensland.
Lorenso, Myrtle and Joseph's parents are Charles or Carlos Cortes (his father possibly name Lorenso) and Susan Elizabeth Byrnes/Burns, married 1890 in Inverell NSW.
Shirley's father Charles and her mother Mary Margaret Olive Curnow married 1925 Queensland. Mary was born 1901 Queensland to Patrick McKeon and Beatrice Mary Curnow.She died 1941 Queensland
Mary's siblings are, Patrick Joseph born 1900 QLD, d 1906 QLD, George Francis Victor born 1904 QLD, Catherine Martha Ann born 1904 QLD, Vincent Gregory b 1909 QLD, Patrick Joseph born 1912 QLD, died 1912 QLD, Austin John Robert born 1905 QLD, d 1907 QLD, James Patrick born 1897 QLD, died 1962 QLD, Bearice died 1911 QLD, Cecil died 1915 QLD and William Phillip died 1956.
