Does your family of Shadbolts have any connection with the gas industry during the 1800's? My Shadbolts are descended from a long line of gas works managers who I have traced back as far as Robert Shadbolt, born about 1817 in Cambridge, who was manager of a gas works in Biggleswade, Bedford, on the 1881 Census. He married Rebecca Sampson in Barnwell, Cambridge in 1837. They were my great great grandparents. My great grandfather, also Robert Shadbolt, was born in 1844 in Cambridge and married Maria Prowse.
