I have seen reference to the owners of the Bedlington colliery in 1850s as Davison, Easton, Anderson, Stodart, Bates & Henderson. Thomas Davison was mentioned in a booked called "A History of Northumberland". 1909. Is there any way one could find out more about this "Thomas Davison" and his family? My family history research is point to this guy as my great great grandfather. Was the colliery sold to someone else between 1855 and 1860? It is my belief that he retired soon after this, moving his entire family to Ontario, Canada.
