Nellie Marion Tenison Cuneo SWA (26 August 1869 – 23 May 1953) was an illustrator and painter who trained in London and Paris.
Her full brother Adolf Heron FRCS LRCP, studied at Cambridge, trained as a doctor and settled at Hayle, Cornwall, in 1947.
[note 2] By 1899 she had saved up enough money to go to Paris to study art, and she enrolled in the Académie Colarossi to train under Whistler, where she met Cyrus Cuneo.
As Cuneo was an American citizen, Tenison ceased to be a British Subject on her marriage under the UK's 1870 Naturalisation Act.
[11] She did not automatically gain US citizenship by marriage, as this was subject to her being eligible to naturalization (as determined by emigration officials whenever she landed in the United States, certain races and immoral persons, etc.
She moved to Dartmoor, then to Cornwall, living first at Halsetown and then in St. Ives, where she bought Down-along House, which she restored, and it became The Copper Kettle (cafe).
[9] Her son Terence was prosecuted for dangerous driving in St. Ives in June 1928, and they were already living at Down-along House.
Peppin and Micklethwait said that She was a capable illustrator, often working in full colour or halftone in a style that had much in common with that of her husband.
