I have managed to find birth, marriage and death details of all the family apart from
- Theophilus and Emma JOYNES after 1871
- Thomas JOYNES after the 1871 census
- Herbert JOYNES after the 1871 census
- James WATTS after the 1911 census
If anyone can give me some clues I would be very grateful.

Just a couple of quick items. If you check the Parish Records here you will find a baptism of Emma Bennett in 1844 in Newland - parents Edmund and Mary.
This seems to fit your 1871 marriage of Emma to Theophilus Joynes where Emma's father's name is given as Edmund - also at Newland.

Doesn't seem to link to any of the Bennett's in my family tree but I may find one later.

This could be Theophilus JOYNES the Elder and the last one might explain his absence from the 1871 Census entry.
