Aeronwy Thomas-Ellis at a poetry reading in New York a year ago
The only daughter of poet Dylan Thomas has died, aged 66, after suffering from cancer.
It is understood Aeronwy Thomas-Ellis, one of the poet's three children who lived in London, passed away peacefully in her sleep.
Writer Paul Ferris, biographer of the late poet, said he was told the news by the Dylan Thomas Trust.
Mr Ferris said: "Aeronwy Ellis was a friend of mine, she was a very self assured character."
He added: "She loved poetry and wrote herself, she also lectured on her father' work in America."
David Woolley, director of the Dylan Thomas Centre in Swansea, worked closely with Aeronwy Thomas-Ellis for many years to promote her father's literary heritage.

He said: "She was great carrier-on of her father's legacy and was fantastically supportive of all the work that Swansea and the Dylan Thomas Centre has done over the past 15 years.
"Nothing that was ever said or done about her father put her off, as obviously a lot of unpleasant things have been said over the years.

"She was genuinely interested in his work and knew a lot about it. She was never fazed by all the talk about what her parents got up to.
"She inherited a certain amount of her father's charm and mischievousness and probably something of her mother's sharp tongue when she wanted to used it.
Aeronwy Thomas-Ellis, who was also known as Aeronwy Ellis, was born in London in March, 1943.
She was heavily involved in the Dylan Thomas trust and often ran poetry reading events and lecture tours about her father's poetry.
It is understood her ashes will be scattered at the Boathouse in Laugharne, Carmarthenshire where the poet and his family lived.
In an interview with BBC Wales to coincide with the 50th anniversary of her Dylan Thomas's death in 1953, she spoke of its effect on her as a child and into adulthood.
"I never really got over it, I always feel there's something missing in my life," she said.
"Some of my best memories are when we walked back silently without speaking to the Boathouse and I just felt so comfortable with him and he obviously felt comfortable with me... because there wasn't any need to speak."
