File NLW MS 13173A. - Achau saint ynys Prydain,

William Owen-Pughe was born in Llanfihangel-y-Pennant, Merioneth and brought up in a farmhouse called Egryn in Ardudwy. He moved to London in 1776, where he committed himself to the London Welsh community, becoming a member of both the Gwyneddigion Society and the Honourable Society of Cymmrodorion. He was made a Fellow of the Society of Antiquaries and corresponded with many scholarly figures of his day. Like his contemporary 'Iolo Morganwg', who greatly influenced him, Pughe held somewhat idiosyncratic ideas concerning the Welsh language and its origins. His own literary output, however, was prolific and included lexicographical works such as A Grammar of the Welsh Language and A Welsh and English Dictionary (both 1803) and translations such as Coll Gwynfa (1819), a Welsh rendering of Milton's 'Paradise Lost'. He was also principal editor of The Myvyrian Archaiology of Wales (1801-1807) and the short-lived periodical Y Greal (1805-1807) and was a regular contributor to the newspapers and magazine publications of his day. Pughe conducted a close relationship with the writer and prophet Joanna Southcott from around 1803 until her death in 1814. Pughe's son Aneurin Owen was a historical scholar who received much of his early education from his father. He edited Ancient Laws and Institutes of Wales; comprising the Laws ... by Howel the Good ... (London, 1841) and was also a major, though unacknowledged, contributor to the prodigious chronicle Brut y Tywysogion (1860).
