My research has come to a halt because I cannot find the parents of my g g grandfather Robert Pinkney.In the various census's he is down as being born in Tudhoe, Fullwell and Durham. He married Jane Telford in 1850 and his father is on the marriage certificate as John Pinkney, coal miner. Robert died in 1890. Any help much appreciated as there are a few folk researching this side of the family. Regards Doreen
