[Footnote ccc: Cecil, the Family name of the Marquis of Salisbury, and of the Earl of Exeter seems to be derived from this ancient British name, anglicized.] Ungenerously he debauched his Daughter, Nest, by whom he had a Son, called Walter. This Son, being upbraided with his illegitimate Birth, by one of his Companions, slew him, and fled to Scotland, where in time he became Lord Steward of that Kingdom; and all the Families of that name in that Country, are descended from that Bastard.[ddd] [Footnote ddd: For this ungenerous proceeding, Fleance was put to Death by Prince Gryffydd, and Nest was put to a menial office; some say, that of a Scullion. She was afterwards married to Trahaern ab Caradoc, Prince of North Wales. Buchanan. Hist. Rer. Scot. p. 193. Dr. Powel's Notes on Giraldus, Lib. I. Chap. 2. p. 88. Edit. 1588.

Having produced the Evidence, I leave the Reader to draw the conclusion. * * * * * ERRATA.

The Reader will be so candid as to excuse the above Errors, and others which may have been overlooked. Those in the Welsh could hardly have been avoided, as the Printer has no Knowledge of the Welsh Tongue. APPENDIX. The following Observations having been omitted, in their proper places; I beg leave to insert them as an Appendix.
