The daughter of an army officer, Major-General John William Augustus Romer, and his wife Marianne, née Cuthbert, she was baptised at Marylebone, Middlesex, now part of the City of Westminster.
[2] Romer gained a reputation mainly as a travel writer, based mainly on the volumes The Rhone, the Darro, and the Guadalquivir.
A Summer Ramble in 1842 (1843, reprinted in 1847), A Pilgrimage to the Temples and Tombs of Egypt, Nubia and Palestine in 1845–6 (1846), and The Bird of Passage, or, Flying Glimpses of Many Lands (1849), the last consisting of "a series of short stories set in Eastern Europe & the Middle East.
[4] Her biography of Marie Thérèse Charlotte, Duchess of Angoulême, was completed after her death by John Doran (1807–1878) and published in 1852 as Filia Dolorosa.
[2] Romer was described by a near-contemporary, the Irish writer Richard Robert Madden, as a "shrewd, lively, mystery-loving, and 'a leetle conceited,' occasional authoress, prone to expatiate rather extensively on themes merely personal, and regarding her own feelings, but always redeeming slight defects of that nature by vivid delineations, and smart, interesting, and entertaining descriptions."
