Elizabeth May Watkin Jones

Elizabeth May Watkin Mrowiec (née Jones; 10 May 1907 – 21 June 1965) was a Welsh teacher and campaigner. She was a leading figure in the protests over the flooding of the Tryweryn Valley.

Life Jones was born on 10 May 1907, in Capel Celyn, where her family lived in the local post office. Her mother was Annie (born Thomas), who was a teacher. Her father, Watkin Jones (Watcyn o Feirion) was the postmaster and a singer who was accompanied by a harp. She grew up in a culture filled home since her father won prizes for his poetry at Eisteddfods.

Jones, Roberts and Welsh politician Gwynfor Evans went to London and Liverpool to protest against the abandonment and flooding of the village. The fate of Capel Celyn was widely reported. The protests was a lost cause and construction began on the dam. The event was significant in Welsh politics.

On 24 May 1958, she married Josef Mrowiec, a Polish soldier who had fled the Nazis and served in the British Army. She visited Poland with him in 1960 and 1962 and, based on these visits, she won the local eisteddfod category with her travel journal.
