The leading interests were those of George King, 3rd Earl of Kingston, and his brother Robert Edward, Baron Erris (afterwards Viscount Lorton); Maurice Mahon, 1st Baron Hartland; Arthur French of French Park, Member since 1783; Sir Edward Crofton of Mote Park, and St. George Caulfeild of Donamon Castle. The independent and Catholic interests were also forces to be reckoned with, as was illustrated in the by-election of 1799, when the Castle employed them in the Unionist cause to secure the return of Thomas Mahon against Col. Robert Edward King, an anti-Unionist who was aspiring to succeed his brother to the county seat.
In 1806 King, then on naval duty in the Caribbean, was sponsored by his brother Henry. The Castle counted it a defeat for them when King was withdrawn in the face of the candidature of Stephen Mahon, younger brother of Thomas Mahon, who was also absent on active service. Mahon’s father thereby secured his return at the modest expense of £1,696 18s.
Number of voters: about 6000 in 1815
