One of the first references to St Faber's is in the text of the manuscript known as The Martyrology of Oengus the Culdee Óengus of Tallaght estimated to have been written at the beginning of the 9th century.
[2] There is a popular myth that St Faber had a pet deer which carried the sacred books that she was entrusted with.
One day, as she was travelling to meet Baron O Phelan at his castle in Boho, the deer was harassed by some hunting hounds.
In order to escape, the deer jumped into the Sillees River and in the process ruined St Fabers books.
[3][4][5] It is reputed that Saint Faber set up a monastery/nunnery in Boho, possibly at the site of the church in Toneel North and introduced Christianity to the area.
