Louis Kinsella was born in Liverpool, Lancashire, England on 10 September 1881 and was baptised 9 days later in Our Lady of Reconciliation Church. He was the son of Richard Kinsella (1844-1930) and Rose Anne Clarke (1857-1946).
Louis' father was a native of Dublin, Ireland and his mother from Liverpool and they married in Liverpool several months before his birth on 23 June 1881 in Our Lady of Reconciliation Church. He was one of eight children born to his parents, his siblings being: Mary (b. 1884), Bernard (b. 1885), George (b. 1888), Elizabeth Ann (b. 1891), Margaret (b. 1894), Edward (b. 1896) and Ellen (b. 1898).
Louis first appears on the 1891 census living at 29 Barmouth Street, Liverpool and his father is described as a marine fireman. On the 1901 census Louis and his family are living at 9 Penistone Terrace, Liverpool and Louis is now described as a steamship stoker.
Louis was married in St Anthony's Church, Liverpool on 23 September 1903 to Ann Barbara Barlow (b. 31 July 1884 in Liverpool). They went on to have three children: Rose Ann (b. February 5, 1904), Julia (b. August 16, 1905) and John (b. July 11, 1908).
On the 1911 census Louis and his family are listed as living at 24 St Martin's Place, Liverpool where he is listed as a marine fireman.
When Louis signed on to the Titanic he gave his address as 7 Canal Walk, Southampton. His last ship had been the Aragon. Kinsella and his colleagues Lloyd, Geer, Witt, Black and Hosgood were taken on at the last minute after six of the "signed-on" crew arrived late for the sailing.
Kinsella died in the sinking. His body, if recovered, was never identified.
His widow Barbara was remarried the following year on 23 July 1913 to John Riley. She died in Liverpool in 1975 aged 90.
His daughter Rose Ann was married in 1923 to Walter Herbert Wilson and had six children, one of which (Louis b. 1926) was named after his lost grandfather. Rose Kinsella Wilson died aged 36 in 1940 in Liverpool. Julia Kinsella, his second daughter, was married in 1928 to Denis O'Brien and had eight (?) children, again one being named after her lost father (Louis, b. 1929); Julia died in Liverpool in 1969. His son John appears to have married and died in Liverpool in the 1980s.
