Hi Andrew,
I have several photographs of Barbara and I can get copies of photos of Walter and Barbara which were taken before he left for Canada, there is also a picture of him with his brother and father.
Walter went ahead to Canada with his father, mother and brother, Barbara and the children were to follow later, but he was, as you have read, killed.
I do not know where the Warner name came from, I know the family farmed in Droyslenden, Lancs but I have not followed his line much further. Would you like me to email the copies of photos rather than post them here?
Cheers
Barbara
