Name of creator
Thomas Iorwerth Ellis (1899-1970), was an academic, teacher and author. He was born in London on 19 December 1899. His father, Thomas Edward Ellis, MP (1859-1899) had died over eight months earlier. His mother, Annie Jane Ellis, née Davies (1873-1942), of Cwrt-mawr, Llangeitho, Cardiganshire, was a descendant of the Davies family of Aberystwyth and Cwrtmawr and the Charles family of Carmarthen. She later married the Rev. Peter Hughes Griffiths (1871-1937).
Ellis was educated at Aberystwyth Grammar School, Westminster School, University College of Wales, Aberystwyth, and Jesus College, Oxford. He was a classics master at Cardiff High School for Boys, 1924-1928, a lecturer at University College, Swansea, 1928-1930, headmaster of Rhyl County School, 1930-1940, and a lecturer in classics at Lampeter, 1940-1941, and Aberystwyth, 1941-1946. He was actively involved with the National Library of Wales and the University of Wales and served as Warden of the Guild of Graduates, 1943-1947. He received an honorary doctorate in 1967, and the OBE in 1968. T. I. Ellis was a founder of Undeb Cymru Fydd, an organization dedicated to preserving Welsh language and culture, and served as its secretary, 1941-1967. He broadcast regularly in both English and Welsh, notably on BBC Radio's Round Britain Quiz. Previously a Calvinistic Methodist, he was confirmed at St Asaph in November 1936, and became a lay reader in the Church in Wales in 1937. He became a member of both the Governing Body and the Representative Body of the Church in Wales.
Ellis edited three volumes of The Letters of T. C. Edwards (Aberystwyth, 1952-1953) and wrote The Development of Higher Education in Wales (Wrexham, 1935) and biographies of his father T. E. Ellis (2 volumes, Liverpool, 1944, 1948), his uncle J. H. Davies (Liverpool, 1963) and Sir Ellis Jones Ellis-Griffith (Llandybïe, 1969). From 1921 he travelled regularly throughout Wales in support of the Welsh Schoolboys' Camp Movement; these journeys became the genesis of his Crwydro series of books (Llandybïe, 1952-1971).
T. I .Ellis married Mary Gwendoline Headley (Mari Ellis) in April 1949 and they had two children, Marged (1950- ) and Rolant (1953- ). He died at his Aberystwyth home on 20 April 1970.
Name of creator
Mary Gwendoline Headley, writer and historian, was born 21 July 1913, the youngest of four children, in Dylife, Montgomeryshire, where her father, the Rev. R. L. Headley (1863?-1955), was vicar; her mother Margaret was from Glanogwen, Caernarvonshire. She was educated at Ysgol John Bright, Llandudno, and the University College of North Wales, Bangor (BA, 1936, and MA, 1938). She became a librarian, joining the National Library of Wales, Aberystwyth, in 1944. In 1949 she married T. I. Ellis (1899-1970) and they had two children, Marged (1950- ) and Rolant (1953- ). She worked to support her husband’s work with Undeb Cymru Fydd and elsewhere, and after his death she also edited several of his books for publication. As a devout Anglican she was active in the Church in Wales and organisations such as the Mothers' Union. She died, in Aberystwyth, on 25 January 2015.
Mari Ellis was a very active writer and reviewer in Welsh periodicals such as Y Llan (which she briefly edited). She also edited 'Colofn y Merched' in Y Llan and the 'Tŷ Ni' magazine published as part of Y Cymro and was secretary and later editor of Yr Angor, the papur bro for the Aberystwyth area. She edited Y Golau Gwan: Llythyrau Tom Ellis A.S. at Annie Davies (Caernarfon, 1999) and with her daughter co-wrote Eglwysi Cymru (Talybont, 1985). Under the name Mari Headley she published three novels, Awelon Darowen (Llandybïe, 1965), Beth yw'r Haf...? (Llandysul, 1974) and Ystyriwch Lili (Talybont, 1988). She researched extensively into 'Yr Hen Bersoniaid Llengar', the group of Anglican clerics supporting Welsh culture in nineteenth century Wales, and their wider circle, and published numerous academic articles. However books on the subject, and a biography of Gwallter Mechain in particular, remain unpublished.
