Nina Frances Layard (Stratford, Essex 1853 – Ipswich 1935) was an English poetess, prehistorian, archaeologist and antiquary who made many important discoveries, and by winning the respect of contemporary academics helped to establish a role for women in her field of expertise. She was one of the first four women to be admitted as Fellow of the Society of Antiquaries of London, in the first year of admission, and was admitted Fellow of the Linnean Society in the second year of women's admission. She was the first woman to be President of the Prehistoric Society of East Anglia.
Nina Layard was the fourth child of Charles Clement Layard and his wife Sarah, née Somes. Her father was first cousin (on his father's side) of Sir Austen Henry Layard (excavator of Nineveh and Nimrud), Edgar Leopold Layard (Curator of the South Africa Museum at Cape Town, and Governor of Fiji), and of Lady Charlotte Guest (Translator of the Mabinogion and collector of ceramics). Nina's grandfather Brownlow Villiers Layard was aide-de-camp and afterwards (1802) private chaplain to the Duke of Kent (and brother of the Governors of Malta and Curaçao and of Lady Lindsey), and was the son of a Dean of Bristol and grandson of the accoucheur Daniel Peter Layard. C.C. Layard was also first cousin (on his mother's side) of Lady Llanover (of the Welsh cultural revival), being the son of Louisa Port, sister of Georgiana (favoured grandniece of Mrs Delany and companion of Fanny Burney), and therefore a descendant of Bernard Granville of Calwich and of Sir Richard Grenville of 'The Revenge'. Nina Layard's mother Sarah Somes was sister of the MPs Samuel Somes and Joseph Somes, who in the 1830s were the largest ship-owners in London and held contracts for convict shipping to Australia. Nina Layard was a sister of the essayist and litterateur George Somes Layard, and therefore the aunt of John Willoughby Layard, psychologist and anthropologist.
