Ralph Moore was born in Winchester, Hampshire, England in the last months of 1890 and his birth was registered in the first quarter of 1891.
He was the eldest child of William Moore (b. 1865), a 1st Class Army Reserve Carman, and his wife Alice (b. 1867), natives of Petworth, Sussex who had married around 1890. He had two siblings: William Charles (b. 1893) and George Harold (b. 1897).
Ralph appears on the 1891 census as a 14-week-old infant when he and his family were living at 1 Penarth Place, St Thomas, Hampshire. His father later became a brewers labourer and the family show up at 19 Hyde Close, St Bartholomew, Hyde, Hampshire on the 1901 census. Ralph perhaps went to sea at a relatively young age and would be absent from the following 1911 census. His parents were by then living at Manor Cottage, Manor Farm, Headbourne Worthy near Winchester, his father now described as an ironmongers shop porter.
When Ralph signed on to the Titanic, on 6 April 1912, he gave his address as Manor Cottage, Headbourne. His previous ship had been the Saxon and as a trimmer he could expect to earn monthly wages of £5, 10s.
Ralph Moore died in the sinking. His body, if recovered, was never identified.
