From South Australian Deaths CD (1836-1915) that I bought 1. George died 25.6.1907 aged 74 2. Naomi died 16.11.1915 aged 73. Both passed away at Mount Gambier, South Australia.There were also 2 Sladdin children died at Mt Gambier. 1. George -10.3.1867 aged 11 months 2. Mary -21.8.1868 aged 5 months. Father was George - mother of George jnr was Mary Ann Nicholls, so guess same for Mary. Hope it helps. Helen.
