Henry Llewelyn (12 September 1855 – 6 August 1933) was a member the Queensland Legislative Council.[1]
Llewelyn was born at Merthyr Tydfil, Wales, to Henry Llewelyn and his wife Elizabeth. He arrived in Australia in 1885 and headed to Gympie to work as a gold miner.[2] In later years he opened a bookshop and stationer which he ran for 34 years.[2]
When the Labour Party starting forming governments in Queensland, it found much of its legislation being blocked by a hostile Council, where members had been appointed for life by successive conservative governments. After a failed referendum in May 1917,[3] Premier Ryan tried a new tactic, and later that year advised the Governor, Sir Hamilton John Goold-Adams, to appoint thirteen new members whose allegiance lay with Labour to the Council.[4]
Llewelyn was one of the thirteen new members, and went on to serve for four and a half years until the Council was abolished in March, 1922.[1]
Llewelyn was twice married, firstly to Eleanor Davies at Wales in 1874.[1] Eleanor died in 1891[5] and he then married Mary Ann McNamee (died 1936)[5] at Gympie in 1895.[1] His marriages resulted in twelve children,[1] including Evan Llewelyn who went on to be the Labor member for the state seat of Toowoomba.[2]
He died in Brisbane in August 1933[2] and was buried at Toowong Cemetery.[6]
