The Pembroke MS. contains a summary of the lives of the Veteriponts, Cliffords, and the Earls of Cumberland, compiled from original documents and family records for the celebrated Lady Anne Countess Dowager of Pembroke, daughter and sole heir of George Clifford, Earl of Cumberland, who died in 1605. This valuable collection gives the most minute particulars and anecdotes connected with the ancient family of the Lords Clifford and their descendants, and being a few years anterior in date to the publication of Dugdale's _Baronage_, the information contained there is entitled to the greatest possible weight as an original and independent authority. In this MS. (a copy of which is in the British Museum, Harl. 6177.) the descendants of Roger, fifth Lord Clifford, are named, but there is no mention of any daughter who formed an alliance with a Wentworth. Afterwards come the issue of the marriage of John, seventh Lord Clifford, with Elizabeth Percy, the only daughter of Henry Lord Percy, surnamed Hotspur, son to Henry Earl of Northumberland. "This Elizabeth Percy was one of the greatest women of her time, both for her birth and her marriages, &c. Their eldest son, Thomas de Clifford, succeeded his father both in his lands and honours, &c. {252} Henry, their second son, died without issue, but is mentioned in the articles of his brother's marriage. Mary Clifford, married to Sir Philip Wentworth, Kt., of whom descended the Lords Wentworth that are now living, and the Earl of Straffod, and the Earl of Cleveland." To which of the above statements must we give credit? If Dugdale be right, there will appear a startling discrepance in the ages of the two persons who are presumed to have formed the alliance in question; whereas if the filiation given in the Pembroke MS. is relied upon, their ages will be quite consistent, and all the other circumstances perfectly in accordance. Roger, fifth Lord Clifford, was born and baptized at Brougham on the 20th of July, 7 Edw. III., 1333; his eldest son Thomas, sixth lord, was born circa 1363, being twenty-six years old at his father's death, which happened on 13th July, 1389, in the fifty-sixth year of his age. Thomas Lord Clifford died on 4th of October, 1392, leaving his son and heir John (seventh Lord Clifford) an infant of about three years old. This lord married the Lady Elizabeth de Percy circa 1413, and his eldest son was born on 20th of August, 1414: he died on 13th March, 1422. The wife of Sir Philip Wentworth, were she a daughter of Roger, fifth Lord Clifford, must have been born between 1363 and 1389; if a daughter of John, seventh Lord Clifford, she must have been born between 1414 and 1422.
