They are in Ulverston in 1881. It looks like they very recently moved there because children were born in the IOM. Son Thomas Edward is 4 here.

After close to 10 years in England, they're back in IOM in 1891. [Peel is not in Marown, so I must have copied something wrong here, or the transcript was wrong, or I was half asleep!]

This is what I have for 1911, where I've noted things that didn't look right.

[* actually they were married 43 yrs with 13 children. No sign that this is a second wife. Also, all 13 appear to be alive in 1911 though not sure about George]

This is Thomas in 1901:

Here they are in 1911. The census indicates 10 born, 5 living, 5 dead. I can find the 5 living and 3 dead, so am missing 2. I have 4 more born after 1911.
