Father and son medal groups

I was first contacted by Chris B for over a decade ago about some research he is conduction. To my pleasant surprise he emailed me again recently but this time it was about some medals he had through a family connection. The two groups are pretty interesting.
The first group was awarded to Ernest Armstrong McCabe who served in WWI and later in WWII. The second group was awarded to his son, Ernest Victor Armstrong, who was aboard the HMAS Sydney when it was sunk off the WA coast.
I soon found the McCabe family on Ancestry and the family tree owner is Ernest Armstrong McCabe's grand daughter.
The returned medal tally is now 1819.
