skeith on Family Tree Circles

I am trying to verify that I have the right John Arthur RICHARDSON to add to my family tree. My grandfather, Claude RICHARDSON was born illegitimate. Have been told by his daughter that his father died in the Boer war. I have found a John Arthur Richardson that did indeed die in the Boer war, was born in 1879 and lived in Yorkshire, the area where my great grandmother lived at that time. However there are at least 2 John Richardsons that died in the boer war. I do not know whether his parents knew that their deceased son had sired a child before he died, I doubt it as there was no contact that I know of between my grandfather and his father's side of the family.
