I haven't been on here for years, as I lost interest in family history for a while, and other things got in the way.
Fascinated to read all this, as I too am descended from John and Lizzie Clamp, through their daughter Florence (my gran).
All the facts everyone on here have posted are correct, thank you. I have pm'ed the OP and hope he will get in touch.
Be interested to hear from anyone else who is also researching the Clamp family. They came to Bucks from Fersfield, Norfolk via Old Newton, Suffolk, and the menfolk all ended up working in the railway works. Lizzie was descended from a huge family of Cheneys in Cublington.
My gran lived in Caledonian Road until her death in 1984.
