Thank you.
Yes William and Elsie had 2 sons:
1) Phillip Henry (1921-1992), lived in the UK his whole life and married Brenda COLE.
2) Ronald (1927-1992), who was sent to live in Australia when he was a child and he never returned to the UK.
We know nothing about William and Elsie except that Elsie had 2 sisters Alice and Mabel (who both subsequently moved to Australia) and her parents names were Alfred and Caroline and they were from the UK.
We can't trace anything else than that.
