Hi,
I hope this thread is still open and that you receive this message!
My name is Emma and the Pat and Paddy you speak of are my Nanna and pop!!
By chance I have stumbled on this website and saw this discussion about my grandfather. Unfortunately, the notice you have already discovered is correct, Pop sadly died approx 4 years ago and we miss him dearly. He was a wonderful man and highly regarded in the navy. The address you found for Onkara st was correct, but my nan moved out shortly after pop died, hence no correspondence would've been answered. Pop was in a nursing home when he died, so the address wasn't correct in the newspaper. However, Nanna (Pat) is still alive (soon to turn 90 years old!) as are my mum (Janet) and my uncle (Brian).
I do hope you receive this and we can communicate further!
King regards,
Emma Clark-Kennedy
P.s I believe he retired a lieutenant commander, not a captain. He also served in the royal navy before the royal Australian navy. I'll have to ask Nanna for more details!
