[7] Her brother Charles (C. C. Oman) became a keeper of the Victoria and Albert Museum and wrote several books on silverware and other domestic metalwork.
[5][10] Oman was quoted as speaking warmly of fellow villager George Bernard Shaw, who had been the Lenantons' first caller at Bride Hall in 1928.
[6] In her writing career of over half a century, Oman produced over 30 books of fiction, history and biography for adults and children.
Her first publication, a book of verse entitled The Menin Road and Other Poems (1919), drew on her war work as a probationary VAD nurse in Oxford, Dorset, London and France in 1918–1919.
However, Oman largely abandoned poetry for the genre of historical fiction; her 1924 debut novel The Road Royal focused on Mary Queen of Scots.
[16] While Oman's historical novels were well received, she would herself later speak of them as "very bad"[12] and from the mid-1930s channelled her interest into the past, writing biographies, beginning with Henrietta Maria (1936), followed by one of Elizabeth of Bohemia: The Winter Queen (1938).
However, Oman produced several historical novels for younger readers, notably Robin Hood: Prince of Outlaws (1937), cited as "one of the most influential of the juvenile literary publications",[25] which remained continuously in print for at least 40 years.
[29] The academic standing of this is clear from the way she was called upon on 10 July 1954 to lecture on Moore to the Anglo-American Conference of Historians at the Institute of Historical Research, University of London.
