Mr Patrick Gill was born in Co Kildare, Ireland, possibly sometime between 1868 and 1875. His exact age is unclear and details about his family are currently unknown. 

Patrick was “married” to Mary Summers, née Wallis (b. 1861), a native of Southampton and daughter of cellarman George Wallis and the former Annie Fielder; there is no record for their marriage and their arrangement appears to have been common-law. The 1911 census stated the couple had been married for 28 years but this is unlikely and may refer to the fact that Mary had a previous marriage; Mary had been married in St Mary’s Church, Southampton on 16 August 1883 to James Summers, a seaman, with whom she had a son, James William (b. 1885), also later a seaman. 

One evening in November 1908 Mary and her younger sister Annie Wallis, a waitress, had been out drinking; when Mary was returning home alone, carrying her sister’s purse, she was violently mugged. At the time she was a resident of Waverley Road in Freemantle and it was stated that her husband Patrick, a ship’s cook, was away at sea aboard the St. Paul.

Patrick and Mary were listed on the 1911 census living at 24 Waverley Road, Freemantle and he was described as a ship's cook; living with them was Mary’s sister, Annie. 

When Gill signed-on to the Titanic on 9 April 1912 he gave his address as 24 Waverley Road, Southampton. His previous ship had been the St. Paul and as a ship's cook he received monthly wages of £5, 10.

Patrick Gill died in the sinking and his body, if recovered, was never identified.
His widow Mary remained in Southampton and was still a resident of 24 Waverley Road in 1935; she died in 1938 aged 76.
