Evening Mark,
I've just stumbled across your enquiry about William Patrick Tobin.
He was my great-uncle and married Florence Bateson and lived in preston until he rejoined the colours as a reservist in the First World war. He was killed on 10 Oct 1916.
I have been trying to find out waht happened to his widow and daughters for years and have quite a bit more information about him.
Feel free to contact me direct if you wish.
Vello.
