Charles le Jeune Jaques was born in 1850 in Spitalfields, but I can't find when he went to Australia. The last time I could find him in London was in the 1861 census at Bancrofts School in Stepney. Have not been able to find him in the 1871 census. The first I can find of him in Australia is in the Victorian Government Gazette in 1872 as a shareholder. He marries in 1873 and again in 1876 after his first wife dies. He has a number of children and dies in Victoria in 1922. So the time frame is between 1861 and 1872. A brother went to Australia in 1854.
