According to Grattan Flood, "About the year 653, St. Gertrude, of Brabant, (daughter of Pepin, Mayor of the Palace), abbess of Nivelle, in Brabant, sent for St. Foillan and St. Ultan, brothers of our celebrated St. Fursey (Patron of Perrone), to teach psalmody to her nuns. These two Irish monks complied with her request, and built an adjoining monastery at Fosse, in the diocese of Liege."
