Llywelun Maddock was born 1870 in Newport, Monmouthshire, the second of the eight children, and eldest son of James Maddock and his wife, Mary Jane Hellyer. James Maddock was agent for the City of Cork Steamship Company and later also a colliery proprietor. He was a nonconformist Liberal who became a member of the Borough Council and a magistrate in the town.

Between 1885 and 1888 Llywelyn was employed as a lad clerk for the Great Western Railway in Newport. In about 1889, he established himself as a photographer in Newport. In 1896 he sailed to Ceylon, where his younger brother, Herbert, was already working in a mercantile business in Colombo. Enroute he met and became engaged to Emma Brownlow King, daughter of the Foundling Hospital artist Emma Brownlow (1832-1905), who was travelling to New Zealand with her family. Between 1896 and 1902, Maddock was chief photographer and branch manager of the Colombo Apothecaries Company in Kandy. He married Emma Brownlow King in the Wesleyan Methodist Church in Kandy on 8 May 1897. In January 1898 Emma returned to New Zealand to give birth to son Llywelyn William (Billy) Maddock. The family then had a long stay in New Zealand in 1899-1900 before Emma and Billy returned to Kandy.

In 1902, the Maddocks returned to Britain, almost certainly on account of Emma’s health. They initially stayed with Llywelyn's parents in Newport, before moving to Sandown on the Isle of Wight. Between 1902 and 1905, Llywelyn worked as a bookseller and stationer in Mottingham, Kent, and then as an accountant in Newport. Emma Maddock died in October 1905. Their son Billy was sent to boarding school and Llywelyn returned to Kandy. Llywelyn returned in 1913, settling in London. During the First World War he was HMS President of the Anti Aircraft Corps (Royal Naval Volunteer Reserve) and was commissioned as a transport officer. After the war, he worked as a government auditor. He died in 1924 in Hornsey Rise, London.
