The youngest of the eleven children of Admiral Thomas Sabine, Baronet Pasley (1804-1884) and his wife Jane Matilda Lily Wynyard, Madalene Pasley was born in 1848, about the time that her father left the Brazilian station to take up duties as superintendent of the Pembroke Dockyard. Madalene married Sir Henry Jenkyns in 1877. Produced when she was 14 years old, Madelene Pasley's "A Selection of British Butterflies and Moths" is a thin duodecimo volume containing observations on British lepidoptera, illustrated with seventeen watercolor sketches. While it was expected that a genteel young woman would acquire basic artistic skills and might be exposed to at least some facets of the study of the natural sciences, Pasley's book was accomplished with unusual skill. Her comments on the phenology, ethology, ecology, and appearance of butterflies are concise and knowledgeable and suggest that Pasley was a true enthusiast.
