The Diaries of Lewis Llewelyn Dillwyn
Lewis Llewelyn Dillwyn (1814-1892) was a scientist and industrialist, before he prioritised his political career. A longstanding Liberal MP, campaigner for the Disestablishment of the Church in Wales, and finally supporter of Cymru Fydd, Dillwyn married the daughter of eminent geologist, Henry De La Beche.
His second daughter was Amy Dillwyn. His diaries, transcribed by Richard Morris, are available below.
