Mr Wilfred George Platt was born in Southampton, Hampshire, England in mid-1894, with his birth being registered in the third quarter of that year. 

He was the son of John Charles Platt (b. circa 1862), a seaman, and Mary Amelia, née Duport (b. circa 1863), both Guernsey-natives who had married around 1889, perhaps in their native Guernsey.

One of four children, Wilfred's siblings were: Mary Amelia (b. 1891), John Charles Nicholas Ozone (b. 14 January 1893) and Ida May (b. 1901). His elder sister Mary had lived apart from the family from a young age, instead living with a paternal aunt and working as a laundress in St Peter's Port, Guernsey.

Wilfred first appears on the 1901 census living at 8 Peto Street, St Mary, Southampton with his family. On the 1911 census Wilfred, then described as an assistant butcher, was listed with his family as living 107 Belgrave Road, Portswood, Southampton. His brother John was also an assistant butcher, he for the White Star Line.

When Wilfred signed-on to the Titanic on 4 April 1912,he gave his address as 107 Belgrade Road, Southampton and his previous ship as the Oceanic. As a scullion he received monthly wages of £3, 10s.

Wilfred Platt died in the sinking and his body, if recovered, was never identified.

What became of Wilfred's parents and sisters after the disaster is unclear and it may be the case that they returned to and resettled in their native Guernsey. Only his brother John is known to have remained in Southampton where he married in 1914 to Mabel Bright and had four children. He later left the sea to become a fitter's mate and died in Southampton in 1970.
