Looking for Parents and Grandparents Names of Alan John Mooney of Bundarra N S W Married 1903 Ii

Looking for information about my grandfathers parents names - and also their grandparents names, please. Anyone who has any information, please contact me, as I'am researching the family history of the Mooney family. Alan John Mooney was born , I think about Sept, 1878 - possible somewhere near Bundarra ? Does anyone know if the family originally came from Ireland - if you have information, please let me know - and possibly the name of County, where the original family came from.
