Hi there, Cyril Rex Blackall (married to Louisa Alam) was my grandfather. I have a copy of Alice Laurette Nowland's birth certificate which states that George Nowland and Alice Blanche Aldwell had 2 previous children, both living , 1 boy(?) & 1 girl (presumably Madeline based on previous posts) at the time of her birth in Camberwell NSW 10/04/1876.
