My grandmother's brother was in the Royal Navy during WW2 and was killed. I know very little about him other than his name and I think I have the year he was born.
By searching his name - William John Miller - online I have come up with one that I think could be him but want to find a way to verify it.
According to this page I found via google, a William John Miller went down with the HMS Blean in Dec 1942 (I was always told the HMS Hood, but there is no record of him in the roll of honour). It lists his number there as well - C/KX.137399 - so what would be the best way to find out conclusively if this is him. I know his parents names and the general area he lived in pre-war.
