Brónach was a holy woman from 6th-century Ireland and a follower of Saint Patrick. She is recognized as the founder and patron of Cell Brónche, a site located in what is now Kilbroney, County Down. Serving as a refuge for sailors shipwrecked in Carlingford Lough, she is also remembered for using a bell to warn people of approaching storms. Her religious community likely began as a nunnery before evolving into a pastoral church that served the local area.
