Bubs you obviously wish us to help you but as we don't know the name of your grandmother or mother it makes it a tad difficult. A couple of us have identified who we think is your mother but we haven't posted her marriage or death. You have on previous posts stated that ELLERY was a family name.
I again ask are you prepared to type up all the information about Albert CAIN published in your aunt's book.
I have spent a lot of time trying to sort out the CAIN births in Victoria. Both a Bridget CAIN and Caroline CAIN had illegitimate children registered and perhaps there may have been more that weren't.
I can certainly understand why didn't receive any response from the Coolamon CAIN [family. They are obviously not connected at all.
Cheers
Cando
