This is great information, thanks to everyone for their help, gives me some leads to go on.
My Father is 87 and Mum died in 2002, so I only remember what I was told as a child.
My family come from West & East London and I have done well on tracing all but my maternal Grandfathers tree.
As people have said, Smith is not an easy name to trace.
Thank you so much
Becky
