hi kellie; sorry for the delay. ive gone through and after once again thinking i had the wrong ada and william i am now positive the ones u found are definetly my ancestors. i was given a bag of my fathers belongings and it was a small lot of treasure. amongst the old roserys and mass books i have my grandfathers (Joseph calder)school qualifying certificate (grade 10 I believe) from 1922 and HIS birth certificate. im still somewhat confused tho as it says ada was born in orange and william in cleveland durham england and were married in woolongong nsw 20th nov 1890. i can only find details of ada m horsley maraying william s calder in orange so im not sure if its the same couple.
