Keyne, St., a pious Cornish virgin, said to have flourished at or near Liskeard towards the close of the 5th century. Her name is preserved in an ancient church and a well, the waters of which possess remarkable virtue. They confer supremacy in married life on whichever of a newly-wedded couple is the first to drink them. The legend is referred to by Fuller, and Southey made it the subject of a jocular ballad. It is given in detail by Cyrus Redding.
