Richard Bertie was the son of David and Linda Wright Yates (née Hewitt).
His father David was born in Alfreton, Derbyshire and his mother Linda in Somercotes. They were married at Shirland St Leonard, Derbyshire, in 1887.
According to the 1911 Census they had had 12 chldren of whom only 11 survived infancy. However, only ten have been traced on the census between 1891 and 1911: Edgar b. 1888 (reg. J/F/M), Richard Bertie b. 1890 bap. Clay Cross 26 April 1890, George b. 1893 (reg. J/F/M), Linda Adelaide b. 1898 (reg. J/F/M), Joseph Henry b. 1900 (reg. J/F/M), Maud b. 1902, Mary b. 1904, Frances b. 1906, Muriel b. Derbyshire 1908 and Joyce b. 1911. Apart from Edgar who was born in North Wingfield, the older children were born in Clay Cross, Derbyshire, Mary, Frances, and Joyce in Mansfield Woodhouse and Muriel in 'Derbyshire.'
In 1890 when Richard was baptised the family home was on New Street, Clay Cross. However, by 1891 David, a coal miner, and Linda were living in Ashover, Derbyshire, with their son Richard (1). Their older son, Edgar, was living in Stirland, Derbyshire, with his grandparents, Henry Broom and his wife.
David was recorded on the 1901 Census as a visitor in a household in Burton upon Trent, while his wife and their five children, Edgar, Richard, George, Linda and Joseph, were in Stretton, Chesterfield.
By 1911 both David and Linda were living on Woodhouse Lane, Skegby, with nine of their children: Edgar and George both coal miner labourers, Linda 'at home', Joseph, Maud, Muriel, Frances, Muriel and Joyce. Richard has not yet been traced on the census.
The later CWGC record gave Richard's parents' address as 59 Portland Street, Mansfield Woodhouse.
However, in 1939 when the England & Wales Register was compiled David and Linda were living in Forest Town, Mansfield Woodhouse, with their youngest daughter Joyce. Linda died in 1946 and David in 1957.
His older brother Edgar may have attested in the Royal Welch Fusiliers (24949) at Mansfield on 22 March 1915. He was 27 years old, working as a coal miner and living in Stanton Hill, Mansfield, with his wife and son. However he was discharged on 9 April 1915 as 'unlikely to become an efficient soldier' citing general debility, myopia and other symptoms of poor health.
