Hello again Deb,
Actually, I'm surprised at just how much can be found from the census about Travellers. I've not looked at Travellers before this and I guess I had a sort of vague idea that the enumerators would not chase them up - but this wasn't the case at all (fortunately for you). There were certainly lots of interesting families around. And it's fascinating how the same names (surnames and forenames) keep turning up.
Your cousins have put together lots of information!
Incidentally, did you see the christening of Selina, your William's little sister, on the IGI.
PINFOLD Selina, bap 22 Feb 1891, Par Cornwall, father Tom Pinfold, mother Sophia Pinfold.
As you say, the IGI has:
John PINFOLD m Harriet JAMES, 2 Aug 1831, Pimperne Dorset
The IGI also has a John and a Harriet having:
Sarah Harriet PENNIFOLD, bap 3 Nov 1833, Saint Nicholas, Brighton, Sussex
I looked at that 1871 census entry which you mentioned (details follow) hoping that tracing some of the people in it might somehow lead to finding Harriet & John, and perhaps Thomas & Sophia in an earlier census. A vain hope!

Henry PENFOLD & Ocean (actually as Penfold!) are in a Caravan in Common Moor Lane, South Molton Devon with Bessie, Henry, Defiance, John, Vastie, Noah, Albert and Leonard.
1881
Henry GESS & Charlotte were in a caravan in East Stonehouse, Devon, with lots of children - but now Charlotte's birthplace is given as Dorset Weymouth. And one daughter, Elizabeth 18, was born in Guernsey ...
1871
Henry GESS & Charlotte and family were in St Andrew Devon - Charlotte's birthplace as Dorset Weymouth
1861
Henry GESS & Charlotte and family are in tents in Camborne Cornwall - Charlotte's birthplace given as Dorset Blandford.
1851
Henry GESS, b Britchingley Sussex, is in Wandsworth with parents Henry & Rebecca and siblings.
There are quite a lot of LDS patron submissions on the IGI for Henry GESS & Charlotte PENFOLD and their family.
But where, oh where, are Thomas & Sophia in anything other than 1891, and where is Thomas's mother Harriet in 1861 and 1851 ...
Regards,
JAP
