Yes I have him on the 1921 census. He and Ellen are together in Barnsley.
I see them now. Although Thomas is crossed out on the census page, and the name
Ernest is clearly written above it.
Please can you confirm - Is Thomas' middle name Edward or Ernest? In your duplicate thread you say his middle name is "possibly"
Edward.

It makes a difference, particularly if he was using Ernest on pre-1891 census records, etc
