Hall was the eldest of seven children born to Benjamin Hall, the dean of Llandaff’s barrister son, and the wealthy ironmaster Richard Crawshay’s daughter Charlotte. Until 1808, when Crawshay bought the 3,000-acre Abercarn estate for the family, he was raised in London, where he and his brothers later became townboys at Westminster with their maternal cousin Richard Franklen, whose father managed his kinsmen the Grants’ Glamorgan estate of Gnoll Castle. In 1810 Hall’s father ‘Slender Ben’, then Member for Totnes, inherited an equal share (three eighths) with Crawshay’s son William in the Cyfarthfa works, the remaining two passing to Crawshay’s nephew Joseph Bailey.
Hall’s relationship with Hawkins was frosty, and after Oxford, where the archbishop of York’s sons, Charles and George Vernon*, became his lifelong friends, he and Franklen toured Wales in 1821 and Scotland and the Lake District in 1822, whence they were summoned back following his brother Henry’s death.
Addressing the Monmouthshire reform meeting he had promoted to the Morgan family’s annoyance, Hall publicized his intention of opposing Beaufort’s sons as anti-reformers at the next opportunity, 17 Mar. 1831.
Are the wishes of those who represent the whole wealth and importance of the county to be spurned and set at naught by the two great houses of Beaufort and Tredegar? ... If the Members do not agree with their constituents they must be ousted in favour of men that will.
Mon. Merlin. 26 Mar. 1831.
He chaired the meeting at Usk, 11 Apr., that adopted William Addams Williams* of Llangibby Castle as the reform candidate for Monmouthshire and, confirming his candidature for Monmouth afterwards, he pledged support for the Grey ministry’s reform bill, economy, retrenchment and the ‘abolition of all sinecures and ill-merited pensions’. He canvassed the Morgan stronghold of Newport, 20 Apr.
Hall addressed reform meetings in October and December 1831, stewarded at the Monmouthshire assembly at the Angel in Abergavenny, 16 Jan. 1832, and in July announced his candidature as a Liberal for Monmouth Boroughs, where he defeated Worcester at the general election in December, but only narrowly avoided having to defend a petition.
