Roger Tobin was born in Lisgibbon, Bansha, Co Tipperary, Ireland on 30 October 1891.
He was the son of Patrick (b. 1856), a farmer, and Margaret Tobin (b. 1855), Tipperary natives who had married around 1887. One of six children, his known siblings were: Patrick (b, 1889), Mary (b. 1890), William (b. 1893) and David (b. 1895).
The 1901 census shows Roger and his family living in house 1, Lisgibbon while the 1911 census shows Patrick, still with his family and unmarried, living at the same address but no profession for him was listed although it was later reported that he worked in a men's drapery, Kelly's. He was a prominent Gaelic sports player, involved with hurling and Gaelic football.
He boarded the Titanic at Queenstown as a third class passenger (ticket number 383121 which cost him £7, 15s, possibly in cabin 38 on F-Dec section C). He was travelling to New York with his sweetheart Katie Peters and was acquainted with two other Tipperary girls, Kate McCarthy and Kate Connolly. He already had cousins in New York and his destination address was 243 East 45th Street, Manhattan, the home address of Katie Peters' sister Mrs John Egan.
On the night of the sinking Katie McCarthy, the only surviving member of their group, recalled that Roger Tobin called by their cabin and told them to get up and dressed and to bring lifebelts but assured them there was no danger. McCarthy said that only she sensed any urgency and whilst she implored the other two girls to follow her, she ended up leaving alone and never saw the other two Kates or Roger again.
Roger Tobin died in the sinking. His body, if recovered, was never identified.
His estate, valued at £39, 6s was administered to his father on 6 December 1912. His father later died in 1928 and his mother in 1933.
