Lleucu

Saint Lleucu was a Welsh saint of the 5th century, perhaps from Llangwyryfon in Ceredigion. The place there is the only settlement known to have been founded by her, and it was for women only. The church there was founded, according to tradition, by disciples of Saint Ursula, a woman of Cornwall martyred in Germany in the 4th century.

Her name is linked with Llanwnnen and Abernant near Carmarthen, and with Betws Lleucu in Ceredigion. The memory of a well of Lleucu near Llangynwyd and another at Flint, now called Ffynnon Cilhaul, is also kept. No other details of her life are known.
