Miss Hannah Naughton was born in Kilcullen, Donoughmore, Co Cork, Ireland on 10 April 1891.

She was the daughter of John Naughton (b. circa 1849), a labourer, and Ellen Connor(s) (b. 1861), both Cork natives who had married on 26 February 1884. 

Born into a Roman Catholic family, Hannah's known siblings were: Martin (b. 8 February 1885), Patrick (b. 25 September 1886), John (b. 11 January 1889), Cornelius (b. 27 July 1893), Michael (b. 25 February 1895), William (b. 17 July 1898) and Bridget (b. 20 January 1901). The baby of the family, Bridget, only just reached her first birthday and died on 29 January 1902.

Hannah and her family appear on the 1901 census living at house 5 in Kilcullen, later being listed at house 3 in the following 1911 census. Hannah was still at home and was described as a scholar. She was in fact privately educated in Crosshaven Convent in Cork and became certified to teach. She took up took up a position in New York as a schoolteacher and would be joining her elder brother Paddy who had emigrated in April the previous year aboard the Teutonic and found work on the railroads. Her maternal aunt Mary Madden also lived in New York. 

Hannah boarded the Titanic at Queenstown as a third class passenger on 11 April 1912, one day after her twenty-first birthday. Her ticket, number 365237, cost £7, 15s and her destination was 433 West 33rd Street, New York City. Travelling with her was another Donoughmore native William Foley.

Hannah Naughton died in the sinking and her body, if recovered, was never identified.

Her grief-stricken family back in Ireland were only to encounter further loss; just after the first anniversary of the sinking her father died on 18 April 1913 aged 64. 

Her brother Paddy later settled in Jersey City, New Jersey and became a naturalised US citizen. He was joined in America by his brother John in October 1922.
