The Walkers of Rotherham were Nonconformists who owed their wealth to successful iron founding, lead manufacture and intermarriage with other industrial dynasties. Joshua, like his elder brother Henry, was trained for an administrative role in the family businesses, in which he inherited partnership shares on his father’s death in 1815. His cousin and co-partner Samuel Walker† had returned himself and Joshua as Members after purchasing the de Crespigny interest in the borough of Aldeburgh for £39,000 in 1818, but the post-war decline in the iron trade that precipitated a reduction in the capital value of their business from over £200,000 in 1821 to under £36,000 in 1832 made their political commitment unsustainable.
A silent anti-Catholic Tory opposed to parliamentary reform, against which he voted, 2 June 1823, Walker attended regularly and divided steadily with Lord Liverpool’s ministry, except when he felt that their policies compromised his religious beliefs (he was a Methodist) or commercial interests in Walker and Company of Rotherham and Sheffield, and in Everett, Walker and Company of London.
Walker cast his customary votes against Catholic relief, 6 May 1827, 12 May 1828, but voted to repeal the Test Acts, 26 Feb. 1828.
It is with extreme pain and reluctance that I find myself compelled to make known to your Lordship that I can neither bring myself to concede to the Catholics that which this bill proposes to give them, nor to believe it will have the effect so confidently anticipated by the legislature with regard to Ireland ... I think I might without hesitation assert that such has been my confidence in His Majesty’s present ministers, that there is no other question upon which I would not surrender my opinion to theirs ... I therefore without hesitation voted in favour of a committee to consider the subject ... [but] my opinions and feeling remain unchanged.
Ibid. ff. 150-1.
Hertford, who authorized his tenure ‘in perfect freedom’ until a suitable replacement was available in May,
he gives me a little touch on his understanding how he was to sit, meaning as a perfect Protestant ... But you know if besides sitting for nothing he is to discuss with me and decide on all questions, even the right of discussing each Member would make a borough valueless. But he retires and unless he makes any remarks we had better let him go over the best bridge and thus an end of it.
Ibid. ff. 152-6.
There is no evidence of Walker’s continued attendance. Out of Parliament, he remained a partner and director of his family’s banking and lead manufacturing companies and played a prominent role in the success of their Lambeth lead works. He sold his interest in the declining iron company in 1833, thus avoiding the bankruptcy that befell his cousin Samuel. In March 1843 Peel dismissed his request for a government post in Canada for his son Edward, then farming in the colony.
