Benjamin was ill in May 1833, though how seriously is not known.

Benjamin had a lithograph portrait of himself drawn and printed which most probably dates from the 1830's. A copy of it survived and was published on 14 August 1964 in the East Grinstead Courier when it was in the possession of Mrs Bertha P. Luxford of Eastbourne who died there on 15 September 1969.

On the evening of Sunday 4, October, 1835, Benjamin preached an uncompromising sermon on the subject of the influence of Roman Catholicism, its doctrine and practices and of similar traits in other denominations. It also contained a plea for tolerance of all religious beliefs. The sermon was published in November under the title The Prevalence of Popery.

On 28 June 1836, Benjamin married, by licence, Charlotte TWISS, at the parish church of St. Mary the Virgin, Speldhurst. The witnesses were Charlotte's brother Daniel and sister Caroline TWISS. Her mother, Mary TWISS née SCOTT (1767-1836), had died earlier in the year (on 20 January) and her father, Robert TWISS on 19 November 1829. The ceremony was performed by the Rector, the Rev. John James Saint, Nonconformist marriages only becoming legal with the introduction of the 1836 Marriage Act which took effect after Benjamin's marriage.

Charlotte's uncle, Richard TWISS, had been author of Travels in Europe, botanist, musician and Fellow of the Royal Society though he was no businessman and lost most of his fortune trying to make paper out of straw. Her grandfather, Francis Richard TWISS (1716-1777) had had to flee with his young wife from his home in Beccles, Suffolk, having voiced support for the Stuarts in the Jacobite Rebellion of 1745. He escaped to Rotterdam acting as an agent for the importing of Yarmouth bloaters and remained there for 25 years until his first wife's death. He then returned to England with his four surviving children, re-establishing contact with his first cousin, Henry Latham, with whom he had maintained business links and with his father also. He returned a very wealthy man, owning warehouses in Rotterdam Harbour and chartering his own ships. Robert's brother (Charlotte's uncle) Francis married Frances KEMBLE, proprietress of a high-society school for girls in Bath, Somerset, and whose sister, Sarah SIDDONS (née KEMBLE), was one of the most famous tragic theatrical actresses of 18th century England. Charlotte's father, Robert TWISS (1760-1829), was born, lived and died in Rotterdam, a merchant and company director of the family firm, Latham and Twiss.
