Hi Ann
Walter's father was my grandmother's brother. I do have Walter's 3 children on my tree - but there a few other gaps there! I didn't have you, for instance!
His uncle Charles was also killed by lightning in the UK in 1915.
If I can find out how to get in touch with you privately, I can certainly help you quite a bit.
Let's see if I can work this out! Or maybe you can figure it out first! .. Sheila
