Thanks Bob,
It's just little details that i'm missing about the dates of birth of Isaac and Mary's children. I have 11 children for them is that right? I don't have the date (only the year) for Emily, Thomas and Arthur. Do you know the full name of their children, I'll list them as I have them
Mary Louisa Graham - 20 Dec 1878 Yetman
Emily Rosina May Graham - 1879 Warialda
William Isaac Alexander Graham - 27 Sep 1880 Warialda
George Albert Graham - 24 Aug 1882 Warialda
Thomas Graham - 1884 Warialda
Amy Rebecca Saville Graham - 12 Jul 1886 Warialda
Richard Graham - 8 May 1888 Warialda
Grace Graham - 9 May 1889 Warialda
Alma Elsie Evelyn Graham - 27 Sep 1891 Warialda
Lucy Madolin Graham - 31 May 1893 Warialda
Arthur Roy Graham - 1895 Warialda
Also do you have a more specific place of birth. On William's birth certificate it just lists Warialda. Do you know the address of the house he may have been born in.
Cheers
Eupham
