[Note 1] On 26 March 1853 he was commissioned as Lieutenant-Colonel Commandant of the new 3rd Royal Surrey Militia, based in Kingston upon Thames.

Challoner stood at the last minute in the Tory Red interest for Great Grimsby in the general election of 31 July 1830, he was unsuccessful coming fourth with 156 votes.

He married, firstly, Anne, eldest daughter of Nicholas Loftus Tottenham, formerly an Irish Member of Parliament, in June 1812.

Lady Blessington circa 1822 when living at Palazzo Belvedere in Naples knew Chaloner Bisse, as he then was known, stating that: His hospitality and kindness made him deservedly respected by all.

[11] Presumably, this was mutual as he was described in Richard Robert Madden's 1855 biography in a chapter entitled 'Society of the Blessingtons at Naples' as 'among the English who frequented the villa'.

Also I know that Col: C: is truly noble & liberal in all his sentiments & actions towards her, but he is not very attractive looking, & indeed I thought on first sight more of his plainness that of his years.
