do you have the reference for the 1901 census where you have found Henry John? The only Henry J I can see gives his place of birth as Priddy in Somerset and has some less than usual names for his children

I can see these children in the free index on the 1911 census as a family group. No parents present, but there are younger children including a 4 year old registered as Martha Jane E V M T Perry june qtr 1907 vol 11a pg 611. The younger Perry children in this family overlap with the children in your John's family from the same index, so don't appear to be the same family.
On his marriage cert, what marital status is given for John - bachelor or widower?
What place of birth does the 1911 show for John?
