Wow! thanks to all for the input and investigations, some great results to digest!
A bit of background;
Leslie Spalding Bates ‘as the story goes’ went into care along with his brother Albert Spalding Kitchener Bates, not sure what age? when Ada could not support them, the Father/s never known, (when Leslie looked before his death he was sad to see no father recorded on birth cert)
At some point both came out of care, Leslie married a Patricia Gleeson and settled in Shoreham by Sea having a family.
It was thought Albert had been placed to emigrate to Australia although no records can be found of him or his Mother Ada at present? Name change looks a possibility too.
I have ordered certs;
Ada birth cert
Leslie marriage cert
Leslie death cert
Thanks again to all, I really appreciate it and could not have got this far without the help
