Hi Bernie,
No, I'm afraid it isn't possible. Veronica Jenkins, nee Lawardorn is deceased and her children aren't interested I don't think.
I met my mother, for the first time, earlier this year. She is Veronica's daughter. Unfortunately, she didn't speak to her mother for many years.
I don't have any contact information for any of the family.
I have provided a lot of information to your Qld rellies. If you have any questions, ask and I'll see what I have in my files.
