Task: Question Generation
Input (English): Passage: A diocesan return of 1563 recorded 145 households in the parish of New Sleaford, while the Compton Census (1676) reveals that New Sleaford had a Conformist population of 576 people, no "Papists", and 6 Non-conformists. There is a widely held local tradition that St Denys' was used during the English Civil War (1642–51) as a barracks for parliamentary troops  who destroyed the interior furnishings. The local historian Trollope stated that the soldiers looted the brass eagle lectern (last recorded in 1622), broke the stained glass windows and the organ, and stole valuables. Whether this damage occurred or not, repairs to the windows and roof were carried out in 1657, paid for by public subscription. Galleries were also added to the church in the 18th century: the south in 1758, west in 1772, and north in 1783–84. In 1772, Edward Evans, a ship's surgeon on HMS Egmont, donated £300 to replace the organ with one built by Samuel Green of London.For most of the 19th century, the Anglican community dominated Sleaford's civic bodies, including the Board of Guardians, who oversaw the workhouse, and the Local Board of Health. Dr Richard Yerburgh and his son, Richard, were vicars in 1809–51 and 1851–82 respectively and had family connections with the local builders Kirk and Parry; Yerburgh and Thomas Parry (one half of the firm) were on the Board of Guardians and were labelled members of a "family party" by opponents during the Board's 1870 elections (they were nonetheless re-elected). They and other local clergymen were key players in the establishment of National schools in Sleaford and Quarrington, which Kirk and Parry built. The Anglican congregation, at an estimated 700 to 800 people in 1851 (St Denys' had enough space for 743 people), was less than half of the size of the nonconformist community, which was probably larger than 2,000 and tended to flourish in poorer parts of the town.The 19th century also witnessed two major restorations to St Denys'. As the congregation expanded, the need for greater space was met with the addition of a new north aisle in 1853. This coincided with a wider restoration project carried out at the cost of £3,500 by Kirk and Parry, which included the demolition of the galleries, the addition of a strainer arch and the relocation of the organ. The church was damaged by an electrical storm in 1884 and parts, including the stone broach spire—one of the oldest in England—were rebuilt by Kirk and Parry in 1885–86. The old organ was sold in 1891 and St Hugh's Chapel and the choir vestry were dedicated to the memory of a local solicitor, Henry Snow, in 1906. Electric lighting was introduced in 1951–53 and extensive restoration work was carried out in 1966, when the organ was rebuilt, and in 1988. Fifty-four solar panels were added in 2008, at the cost of £70,000, and by 2011 were able to cover the church's electricity bill.
Output (English): What are the last names of the two individuals who were nonetheless re-elected despite being labelled members of a "family party" by opponents during the Board's 1870 elections?
