Hi Bobmills6, my own family line also originates with 19th century Smiths. I have written a book on the Romany Smith family, though it is not published just yet. Checked my research files and this is the info I have for your Moses, starting with his baptism and that of his siblings:
1] Thomas Smith, son of Benjamin and Mary Smith ‘Trampers’ baptised at Datchworth, Hertfordshire on 7th Feb 1808.
2] Moses Smith, son of Benjamin Smith, and Mary, baptised at Wheathampstead, Hertfordshire on 12th February 1815.
3] James Smith, son of Benjamin Smith ‘a stranger’ and Mary, baptised at Aspeden, Hertfordshire on 28 Sep 1817.
4] Sylvester Smith, daughter of Benjamin Smith ‘labourer’ and Mary, baptised at Bengeo, Hertfordshire on 1 July 1821.
5] Caroline Smith, daughter of Benjamin Smith and Mary, baptised at Graveley, Hertfordshire on 9 oct 1825.
6] Sharlender Smith, aged 12, daughter of Benjamin Smith ‘Tinker’ and Mary, baptised at Datchworth, Hertfordshire on 27 July 1828.
7] Jemima Smith, daughter of Benjamin Smith ‘Tinker’ and Mary, baptised at Datchworth, Hertfordshire on 18 July 1830.
8] George Henry Smith, son of Benjamin Smith ‘Brazier’ and Mary baptised at Hertford All Saints on 17 Feb 1833.
He might be the Moses Smith who married Rebecca Harris at Thorley, Hertford, 13 Oct 1845. He is stopped alongside several families, including Harrises, on the 1861 census:
1861 Census, caravan, Chipping Barnet, Hertfordshire
Moses Smith 42 Tinman and brazier at the Fair
Fanny Smith 40 wife
William Mills, 26 mat maker at the fair
Sarah Mills, 24 wife, mat maker at the fair
Charles Grosvener, 16, lodger, mat maker at the fair
John Mills, son, 4
Alice Mills, dau, 3,
A John Anderson and his family are also there that year and he had appeared in the following newspaper report with Moses eight year earlier:
Chelmsford Chronicle, Essex 14th October 1853 - Saffron Waldon – 'William Hoadley, Moses Smith, C. Lee, Wn. Stone, and John Anderson, gipsies, were convicted of lighting a fire and creating a breach of the peace at Little Ilford’
As you already have him on the 1881 census, and I see in your other thread someone else has found him in 1891 at the ‘Hole’ in Loughton, I wont replicate that info again. He died there later that same year, death cert ref:
Moses Smith, age 65, Oct-Dec 1891 Epping, Essex, Vol 4A Page 153.
Might be worth ordering a copy of that that if you don’t have it already. Death was also reported in his local paper:
Chelmsford Chronicle, Essex October 1891 - Death of a Local Character.—Moses Smith is dead. In Loughton and its neighbourhood he was well known as an " eccentric." He followed the avocation of a travelling tinker, and had lived for a number of years at a place called the "Hole."
