| Carlisle | 12 Apr. 1721 – 1727 |
Sheriff, Cumb. 1732 – 33; alderman and several times mayor of Carlisle.
Aglionby came of an ancient Cumberland family, connected with Carlisle, of which his grandfather had been recorder. He contested Carlisle successfully in 1721 and 1722 with the support of Lord Carlisle, but, quarrelling with his patron, he did not stand in 1727. He then attached himself to Lord Lonsdale which, Lonsdale remarked,
served both our purposes; it served his to make him considerable at Carlisle and to form an interest there for himself if I did not oppose him; and it served mine to keep up an interest there against Lord Carlisle, without my being at the trouble of doing it myself, and which I could make use of if I saw occasion for it.1To Sir Jas. Lowther, 16 Oct. 1733, B. Bonsall, Cumb. and Westmld. Elections, 9.
But when applied to by Aglionby for support in standing for Carlisle in 1734, Lonsdale refused to meddle in the election,2Ibid. at which Aglionby was defeated, never standing again. He died 7 Aug. 1759.
