Of a royal family of Scotland, she was very beautiful, endowed with every virtue, and desirous to consecrate herself a spouse to Christ.

Meeting with great opposition from her parents and worldly friends, she underwent on that account many persecutions and hardships, which she overcame by patience and constancy.

Butler says she made her profession in a great nunnery in Fife, and that a church in Glasgow is still called St Kennock's Kirk.

Though an only daughter, and the heiress of a rich and noble family, fearing lest the poison which lurks in the enjoyment of perishable goods, should secretly steal into her affections, or the noise of the world should be a hinderance to her attention to heavenly things and spiritual exercises, she rejected all solicitations of suitors and worldly friends, and, in the bloom of life, made an entire sacrifice of herself to God, by making her religious profession in a great nunnery, in the county of Fife.

In this holy state, by an extraordinary love of poverty and mortification, a wonderful gift of prayer, and purity or singleness of heart, she attained to the perfection of all virtues.

Several miracles which she wrought made her name famous among men, and she passed to God in a good old age, in the year 1007.
