Mr Thomas Millar was born on 11 August 1879 in Carrickfergus, Co Antrim, Ireland (modern-day Northern Ireland), a market town situated on Belfast Lough which is dominated by the Norman fort, Carrickfergus Castle.
He was the son of Thomas Millar, a sailor, and Agnes McGowan who had married in 1864 and he grew up in a Church of Ireland household.
His known siblings were: Matilda Jane (b. 9 July 1865), Samuel (b. 26 June 1868), Sarah (b. 16 July 1871) and Isabella (b. 18 April 1877).
Thomas served his apprenticeship with Harland & Wolff and subsequently worked for Vickers of Barrow, Workman, Clark & Co. of Belfast and later again Harland & Wolff.
He was married in St Mary's Church, Belfast on 1 October 1900 to Jane "Jennie" Ruddock (b. 30 June 1879 in Belfast), the daughter of William Ruddock, a tenter and artisan, and the former Margaret Atkinson; on the occasion Millar was described as an engineer and he and his bride's respective addresses were given as 23 Upper Canning Street(1) and 19 Meadow Street.
Thomas and Jennie would have two sons: Thomas (b. 9 February 1901) and William Ruddock (b. 5 March 1907).
Thomas was absent from the 1901 census of Ireland but his wife and first son were listed at 10 Meadow Street in the Dock Ward of Belfast City, the home of his wife's widowed father and several of her siblings. By the time of the 1911 census Thomas and his family were resident at 14 Hillman Street, also in the Dock Ward, and he was described as a fitter. He reportedly helped build the engines for both Olympic and Titanic.
Whilst a resident of 27 Hillman Street Thomas became a widower when his wife Jennie died aged 32 on 18 January 1912 as a result of pulmonary tuberculosis. He decided to go to sea shortly after, leaving his sons with an aunt. Before he left on Titanic he gave each of his sons two new pennies which are still in the possession of current day family.
When he signed on to the Titanic in Southampton on 6 April 1912 Millar gave his address as 19 Meadow Street, Belfast1. His previous ship had been the Gothland and as assistant deck engineer he could expect monthly wages of £9, 10s. The Titanic was reportedly only his second sea voyage.
Thomas Millar died in the sinking and his body, if recovered, was never identified.
