In 1845, when she was 44 years old, she married as his second wife, Sir Thomas Wilde, later Baron Truro (7 July 1782 – 11 November 1855).

Lady Truro had strong connections with Ramsgate, Kent, residing at Mount Albion House on the East Cliff.

In later years, Lady Truro suffered from severe bouts of asthma and usually spent the autumn on the continent.

She returned to her town residence in Eaton Square, London, where she died suddenly on 21 May 1866, eleven years after her husband.

The Thanet Advertiser remembered her as: "a lady of strict business habits, and rather reserved in manner, of exceedingly good general information, living, while at Ramsgate, in a very quiet and unostentatious way”.
