Augusta Emma Wilde, Baroness Truro

Her parents were married at Rome, and afterwards at St George's, Hanover Square. Upon the death of their father, Augusta's brother Augustus d’Este claimed the dukedom; but the House of Lords decided against the claim, on the grounds of the invalidity of the prince’s marriage, it having been contracted without the consent of the Crown, as required by the Royal Marriages Act 1772

In 1845, when she was 44 years old and he was 63, she married as his second wife Sir Thomas Wilde, later 1st Baron Truro (7 July 1782 – 11 November 1858). They had no children together, although Lord Truro had three surviving children by his first marriage.

Lady Truro had strong connections with Ramsgate, Kent, residing at Mount Albion House on the East Cliff. She owned a considerable amount of valuable property in the town, mostly situated on the Mount Albion Estate.

In later years, Lady Truro suffered from severe bouts of asthma and normally spent the autumn on the continent. She returned to her town residence in Eaton Square, London, where she died suddenly on 21 May 1866, six 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”.[1]

The d'Este Mausoleum, St. Laurence Churchyard, Ramsgate.

The funeral took place on the afternoon of Monday 28 May 1866 at St Laurence Church, Ramsgate.[2] She is interred in the family mausoleum (Grade II listed).[3] She left an estate valued at around £70,000, of which over £40,000 was left to charity.[4]
