Faces from the past Friday - the four cousins

While researching the cousins that lost their life in WWI, I thought a lot about what it would have been like for these four young Australian men on the other side of the world. 

Who were the four young men? Well they were:

Harold George McKerihan (husband of my 1st cousin 1x removed)
Guy Sydney Connor (my 2nd cousin 1x removed)
Henry Surman (Harry) Connor (my 2nd cousin 1x removed)
David Ernest McCann (my 1st cousin 3x removed)

That doesn't tell me much. It's true that I did not know them, they died long before I was born however I feel a need to write something of them.
