I think I've found a DOD for a player not on the list. For some reason, 4 years ago an anonymous editor changed Kevin Hart's (Fitzroy 1947-49, 19 games, Carlton 1950, 5 games) Wikipedia article to say "date of death unknown". As he was born in 1927, I thought this was strange, as he could well be still alive. So I started checking, and found an obituary in The Age and a record at GMCT of his cremation that say he died on 6 October 2016.
Also, this article says that he is the brother of Eddie Hart, and hence Don and Arthur too, which doesn't seem to have been recorded previously.

Whilst the obit doesn't mention his football career, the cremation record does match the full name and date of birth that we have. I've tweeted this info to Tony De Bolfo, Blueseum, Spirit of Carlton, the Brisbane Lions and the FBL Historical Society but haven't had any acknowledgement.Also, this article says that he is the brother of Eddie Hart, and hence Don and Arthur too, which doesn't seem to have been recorded previously.
