"Grace." A ghostly person connected with the lake and the house of Glasryn. One story is to the effect, that on a certain evening she forgot to close the well (Ffynnon Grassi), and that when the gushing waters had formed the lake, poor Grassi, overcome with remorse, wandered up and down the high ground of Cae'r Ladi, moaning and weeping. There, in fact, she is still at times to be heard lamenting her fate, especially at two o'clock in the early morning. Some people say that she is also to be seen about the lake. But on the whole her visits appear to have been most frequent and troublesome at the house itself. She appears as a tall lady with well marked features and large bright eyes, dressed in white silk and a white velvet bonnet.
In a different story, when the water broke forth to form Glasryn Lake, the fairies seized Grassi and changed her into a swan, and that she continued in that form to live on the lake six-score years, and that when at length she died, she loudly lamented her lot: that cry is still to be heard at night.
