After his death, she kept his embalmed heart, contained in a casket of ivory and silver, with her for the rest of her life, and it was buried alongside her when she died.
In line with this devotion to her late husband, she named the abbey Dulce Cor (Latin for Sweet Heart).
He was charged several times with enticing to "papistrie" from 1578 to 1605, until finally he was arrested in 1605, in spite of the resistance of the whole countryside, and transported to Edinburgh, where he was tried and sentenced to exile.
Although the present buildings date from the late 18th century, there was an earlier mill built by and for the monks of the abbey which serviced the surrounding farms.
Surrounded by rich and fertile grazing and arable land, they became increasingly expert and systematic in their farming and breeding methods.
Like all Cistercian abbeys, they made their mark, not only on the religious life of the district but on the ways of local farmers and influenced agriculture in the surrounding areas.
