Junor and her brother William were born in Demerara in the British colony of Guyana, where their father owned a timber estate with sixty enslaved people.[4] In 1816, Hugh Junor returned with his children, though apparently not with their mother, to his native Scotland and settled in Fortrose, on the Black Isle,[3] and had both children baptised at Rosemarkie.[4] Her father died in 1823 and bequeathed his estate in Essequibo to his legitimate son Colin; his widow remarried and named one of her sons Hugh Junor Browne in honour of her first husband.[5]
Junor went to school in Fortrose and won prizes for penmanship. She later lived in Edinburgh and Brixton, London, where she worked as a governess. She never married but had one daughter, Emma McGregor,[3] who was baptised at St George Middlesex in 1838.[4] She returned to Fortrose in the 1850s. Her brother William married a woman from Glasgow and emigrated to Argentina as a missionary for the Methodist Church.[2] Junor died on 20 April 1861 and is buried in Rosemarkie churchyard.[3][6]
