My Ancestors also moved to Bedlington From Norfolk, One family (Slaughter) moved between 1860 and 1870 and the other one (Neave) moved after the head of house died, his wife (A daughter of the Slaughter family) brought her 8 children there, some of who went straight to work in the Mines. I heard that the Collieries were offering some sort of assisted passage (by Rail) to people in Norfolk (where agricultural workers were being replaced by machines) to the North east where more Miners were needed for the expanding coal industry. I would like to find some evidence of this, but haven't found any yet.
