Andrew Behan has researched this man:
Sir Daniel Thomas Keymer, O.B.E., was born on 24 January 1857 in Hackney, the eldest of the five children of Daniel Joseph Keymer and Eliza Keymer née Cooper. He was baptised on 8 March 1857 at John's Church, Bethnal Green and the baptismal records show the family living at 3 North Street, Bethnal Green and his father's occupation as a Clerk. The 1881 census shows him living with his parents and siblings at 16 St Thomas Road, South Hackney and his occupation was recorded as a Tie Manufacturer employing 30 hands whilst his father is shown as an East India Agent.
Electoral registers show that by 1894 he had moved to 7 Warwick Road, Upper Clapton. On 12 September 1899 he was married at the St John of Jerusalem Church, South Hackney when he was 42 years old and living at The Beeches, Warwick Road, Upper Clapton, to 22 years old Louisa Richardson of 'Richboro', King Edward Road, South Hackney. His occupation was recorded as an East India Trader. On 15 December 1900 their daughter, Enid Louise Keymer, was born and the 1901 census shows them all living at 7 Warwick Road, Upper Clapton together with a cook, a parlour maid and a nurse. His occupation was given as an East India & Colonial Agent. They had two sons, Kenneth Cooper Keymer, who was born on 5 February 1906 and Ronald Cooper Keymer, who was born on 1 January 1911.
The 1911 census confirms that by then they had had a total of five children, but only the three mentioned above were still alive and they were still living at 7 Warwick Road, Upper Clapton. The London Gazette confirms that he was awarded a knighthood in the 1923 King's Birthday Honours List for public and political services in Hackney. Probate records state that he died, aged 76 years, on 15 February 1933 at 7 Warwick Road and his estate totalled £28,992-9s-4d.
