There is only 1 Henry Jackson,born c 1884, listed in 1901 with a father Thomas in all England.
Living at Tonge. Father a farmer
There may be others that don't show of course, if he's not living with his father, or mistranscribed.
There are a few more showing up in 1891.
Interestingly, I think it shows up a flaw in the search mechanism for a well known site.
In 1891, if you search for Henry born 1884 +-1, father Thomas, he doesn't appear, but if you search for Thomas, Henry is clearly
there in the family.
Thomas is down as Thos, which is recognised as an alternative to Thomas in the first field, but not when you use it in the 'father' field.
