Hello,
Came across this site and thread by chance. Georgina Donegan was my grandmother and John my grandfather. They had three children, two boys and a girl - all deceased now- my mother being the girl. John D left the family in about 1942, Ena got a judicial separation, unusual at the time, due to his behaviour. Looking at this thread, it seems that he went on to have more children. This is huge, because nothing was ever heard of him again after he left. They stayed in touch with Gabrielle (Aunty Gaby). Be great to hear more. I have a few of my mother's memories I could share.
