Mr Michael Linehan was born Knocknageeha, Derragh, Co Cork, Ireland around 1891.
He was the son of Bartholomew Linehan (b. circa 1836), a farmer. The identity of his mother is not certain but is believed to have been a woman named Margaret (née Gavin?) and they were possibly married in 1886. Whatever her identity she had died prior to 1901.
Michael's known siblings were: Margaret (b. 1886), Jeremiah (b. 1889), John (b. 1893) and Bartholomew (b. 1896).
Michael appears on the 1901 census living at house 9 in Knocknageeha. His father, sister Margaret and brother Bart were living at house 6 in Knocknageeha by the time of the 1911 census with Michael absent and listed elsewhere as a farm servant in nearby Tullig, Drishane, Cork.
He boarded the Titanic at Queenstown on 11 April 1912 as a third class passenger (ticket number 330971 which cost £7, 17s, 7d). Travelling with him were others from his general locale in Cork: Bridget Bradley, Patrick Denis O'Connell, Nora O'Leary and Daniel Buckley. He is believed to have shared a cabin with his fellow Cork men.
Michael Linehan died in the disaster. His body, if recovered, has never been identified.
