[3] His mother died aged 73 in 1828 at Langdon Hall, Devon, the family seat in the parish of Wembury, about 5 miles (8.0 km) from Plymouth.

[9][10] She had bought West Wembury farm, from the Lockyer family, and owned also the barton at Down Thomas, where the manor belonged to Edmund Pollexfen Bastard.

[12] During 1839 John George Cooke (1819–1880) heard from Calmady and Sir William Molesworth, 8th Baronet of their interest in a "New Plymouth" project of settlement in New Zealand.

[20] In debate with Richard Crowder in Plymouth on 15 July at a noisy meeting, Calmady announced political principles, including broader suffrage and the secret ballot, associated with the Chartists.

The celebrated double portrait of her two eldest daughters as young children resulted from a visit she made, on Lewis's advice, to the studio of Thomas Lawrence.

[29] Lawrence corresponded with Emily at Woodcote House, Calmady's residence in Hampshire, in the region of Alresford and Bramdean, near Brookwood Park and the London-Southampton road.
