Is there anyone who has any idea about these persons?

The firm of Jarrold and Sons has been in existence since
1770, but in the early days of the temperance movement
was simply an ordinary country printing establishment.
In 1836 Mr. Samuel Jarrold (1805-1874) became a total
abstainer, and until his death was a warm advocate of the
movement. To meet a great want of the new movement Mr.
Jarrold published a valuable series of temperance tracts, and
these were followed by the well-known Monthly Visitor, which
has been so extensively circulated in hundreds of cities and
towns as an adapted local magazine. Under Royal warrant
the firm have become School Stationers at Norwich to H.M.
the King. Their trade in Bibles, Reward Books, and litera-
ture of a pure and elevating character must be enormous,
and in addition they are the patentees of the Marston
Return Address Label, and a new system of producing
coloured picture post cards. In 1902 the firm was made
a limited liability company, the whole of the directors being
total abstainers, Mr. W. T. F. Jarrold (Chairman), Mr.
T. H. C. Jarrold and Mr. John E. Moorhouse.

Sorry, but what I actually want to know are the full names of these people.
