This is off another board but I am stumped so wonder if anyone can solve it

William Thomson (variable spelling) appears in the Welsh census
1861 - THOMSON POB "Midley" (Dudley) and YOB 1836
1871 - THOMASON POB Dudley .. YOB 1835
1881 - THOMPSON POB Dudley ... YOB 1834
1891 - THOMPSON POB: NK, Staffordshire .. YOB 1833 (he was living with his Son George - 13, and Daughter Jane - 16)
1901 - THOMPSON POB Brynmawr .. YOB 1830
William was a collier, married in Wales, father Richard Tomson, farmer.
So can anyone find him in the 1841/51 perhaps born abt 1834ish, father Richard.
I wondered if he was from Staffordshire but near to Dudley, rather than Dudley itself?
