I have callows in the family but am having trouble tracing the line. There was a father Unknown Callow who had 3 sons (Jack, Harry, Unknown) and 2 daughters (Florence and Margaret). The father and 3 son's all fought in the boer war and all went to the Sandhurst Military academy. Harry married a Jessie Campbell who was Australian born. Anyone able to fill in the gaps for the family? I think Harry took a bullet during the war and died in 1934 of a heart condition.
