PATRICK KEVIN Barrett 1894 - 1965 born Cork, Ireland, died Australia

I am having trouble finding any information on Patrick Barrett. He was a soldier in WWI and from non.-substantiated evidence, was married twice. His second wife was Doris Fairhall and they had three children.

His father's name was also Patrick, his mother's name was Bridget Mary (maiden name unknown) I have also been told that he had a brother John but I have no information on him either.

I'm trying to find any information on this line as I cannot locate anything.

Thank you
Sally
