Edith Bernal, Lady Blake (née Osborne; 7 February 1846 – 18 April 1926) was an Irish botanical illustrator and writer, noted for her work on the flora and fauna of countries such as The Bahamas, Jamaica and Ceylon.

[2] Artists often stayed at Newtown Anner, including Thomas Shotter Boys and Alexandre Calame, and it is possible the sisters received tuition from them.

[3] Edith developed an interest in botany around this time, corresponding over the years with Newtown Anner's garden designer Joseph Paxton.

During these visits she took sketches of the local architecture, art, and culture which she published in her first book Twelve months in southern Europe (1876).

Blake's husband received his first appointment in the British colonial service in 1884, as governor of The Bahamas 1884 to 1887, followed by Newfoundland 1887 to 1888, Jamaica 1889 to 1897, Hong Kong 1898 to 1903, and Ceylon 1903 to 1907.

196 of her studies of the life stages of Jamaican lepidoptera are in the entomology library of the Natural History Museum, London, and more of her work is held by the National Botanic Gardens, Dublin.

She contributed to a number of English and American scientific journals, and was heavily involved in the development of the countries the couple lived in.

As Lady Blake she published 3 plays: Samhain's eve, The quest of Edain, and The swan, all adapted from Irish mythology.
