The couple had three children: Emily Ruth (b. 25 June 1870); Annie Georgina (b. 5 June 1873); and John Alfred (b. 21 November 1880). Emily Ruth was born at Chapman's mother's home in Montpelier Place, Knightsbridge; Annie Georgina was born at South Bruton Mews, Mayfair; and John Alfred was born in the Berkshire village of Bray. John was born crippled. The Chapmans sought medical help for their son John at a London hospital before later placing him in the care of an institution for the physically disabled close to Windsor.
