Gilbert Rimmer was born in Liverpool, Lancashire, England in 1883 and his birth was registered in the third quarter of that year. He was the son of John Rimmer (1844-) and Alice Witter (1848-).
His mother and father were from Scarisbrick and Halsall in Lancashire, respectively and they were married in 1866, producing eleven children, six of whom lived past infancy. Their known children, besides Gilbert were: Thomas (b. 1867), William (b. 1869), John (b. 1871), Charles Wesley (b. 1875), Elizabeth (b. 1878), William (b. 1880), Alice Ann (b. 1880), Jane (b. 1882) and Elsie (b. 1891).
Gilbert first appears on the 1891 census and at that time he and his family were living at 59 Rushton (?) Street, Everton and his father was described as a casker (in a brewery house). They have relocated to 429 Scotland Road, Liverpool by the time of the 1901 census and Gilbert appears also to be working in a brewery.
Gilbert was married in Liverpool in 1907 to Mary Elizabeth Adams (b. 1884 in Walton, Liverpool). The couple subsequently moved to Southampton where child, a son called Gilbert Edward Lingarde, was born on 9 November 1908. The 1911 census shows Gilbert's wife and son living at 31 New Road, Southampton.
When he signed-on to the Titanic, on 4 April 1912, Gilbert gave his address as 50 Cranbury Avenue, (Southampton). His last ship had been the Oceanic. As a saloon steward he received monthly wages of £3 15s.
Rimmer died in the sinking. His body, if recovered, was never identified. The following death notice appeared in The Hampshire Independent (unknown date):
RIMMER--Gilbert Rimmer, of 50, Cranbury Avenue, Southampton, who lost his life on s.s. Titanic, April 15th. Sadly missed by his sorrowing wife and child.
Gilbert's widow Elizabeth may have been pregnant at the time of the disaster, giving birth to a son named Leslie Charles shortly after. What became of Elizabeth is uncertain but she may have remarried and relocated north to Liverpool. His son Gilbert died in Chester in 1982.
