I am looking for any and all information on a William Henry Riley. William was born c1890 in Collingwood, Melbourne and died fighting in World War 1 on 7 November 1917. He is buried at Polygon Wood, Belgium and his service record number is 5180. His daughter is Irene and perhaps another daughter Grace?
I would appreciate any and all family information on him as I have very little, esppecially parents names, siblings, etc.
