Irish writer Nesca Adeline Robb is born in Belfast on May 27, 1905.

Robb is the daughter of the managing director of J. Robb & Co., Charles Robb and his wife Agnes (née Arnold), daughter of Dr. Wilberforce Arnold. She attends Richmond Lodge, and then Somerville College, Oxford to study modern languages in 1924. She receives a Bachelor of Arts (BA) in 1927, a Master of Arts (MA) in 1931 and then a Doctor of Philosophy (DPhil) in 1932. She publishes her research as Neoplatonism of the Italian renaissance in 1935. She is a member of the Northern Ireland committee of the National Trust, to which she presents the family home, Lisnabreeny House, Castlereagh, in 1937. She engages in social and voluntary work for a time, before moving to London in 1938 to take up a position at the London Institute of Italian Studies.

Robb publishes her first volume with Wiley-Blackwell in 1939 as Poems. She is the registrar and advisory officer to the Women’s Employment Federation between 1940 and 1944, during which time she writes a partial account of her experiences in An Ulsterwoman in England in 1942. She returns to Northern Ireland in 1944, working for a number of public bodies including International PEN and the National Trust, and writing. She serves as a member of the Committee for the Encouragement of Music and the Arts in 1951. In the same year she edits The Arts in Ulster with John Hewitt and Sam Hanna Bell, which argues that any mention of politics should be excluded from collections.

In 1962 and 1966 Robb produces a large two-volume history of William of Orange. In 1963, she becomes a member of the Maatschappij der Nederlandse Letterkunde. She produces a final volume of poetry in 1970, Ards eclogues, and is elected a Fellow of the Royal Society of Literature. Over her lifetime she writes seven volumes of poetry, history and art criticism.
