Alis Mallt Williams

Alice Matilda Langland Williams, more commonly known as Alys Mallt and Y Fonesig Mallt (4 October 1867 – 28 October 1950), was a Welsh political writer and celtophile. She was born in Brecknockshire to an English-speaking family, but learned the Welsh language when influenced by the circle of Welsh heiress Augusta Hall, Baroness Llanover.

Throughout her adult life, Williams was part of a campaign for Welsh home rule. She supported Welshness in dress and speech. She also joined Welsh nationalist organisations, such as Cymru Fydd and Plaid Cymru. She spoke admiringly for the zeal of Irish nationalists.
