Hi Aghadowey,
You did find the correct James Robinson marriage, due to checking occupation, and parentage and area of marriage.
As for the census, I find it curious that James is there, but not his wife. Thomasena is there but not her parents although that is not as curious. But I couldn't find the parents elsewhere or James' wife.
I paid for the death of Thomas and it was the correct person. He is married so Sarah died after him, which was Feb 25, 1957. They had a son James as well as he was present at his father's death and a J. Robinson was present at Thomasena's death (she married Harold Henshaw).
thanks for your help
Peggy
