DonnaC on Family Tree Circles

Looking for the parents of my great grandfather Albert Giles born 15 oct 1870 at Cherry Gardens South Australia? died 20 Aug 1948 Parkside, Sth Aust, Australia married Mary Coulter 1900 at Warnabool, Victoria, children Albert Giles Coulter (born before they were Married), Doris Frances Alexandra (born in Victoria) rest of children born in South Australia, Douglas Adelaide, Ada Margarette, Leslie William George, Grace Pretoria, David Allan, Bernard Anzac, there may have been one other. Most of the children were born at Brownhill Creek South Australia where they lived, Albert was a gardener, he was admitted to Parkside Mental Hospitall in 1919 and died there. Any information would be great as I have hit a very deep brick wall with this branch. Thankyou
