As before stated, the second son of William Morgan (described in the annexed pedigree as heir of Coed-y-gorres in 1678,) was Thomas, who married Dorothy, the daughter of David Mathew, Esq., of Llandaff, by his wife Joan, the daughter of Sir Edward Stradling, Bart., of St. Donat’s. The only issue of this marriage, so far as I have been able to ascertain, was David Morgan, the unfortunate subject of this paper; and who thus appears to have been closely allied to the two distinguished families of Mathew and Stradling, then among the most wealthy and influential in Wales. The Mathew family boasted of an illustrious descent, being derived from Gwaethvoed, Prince of Cardigan; and one of their direct ancestors being Sir David Mathew, of Llandaff, who was one of the most distinguished men of his time, and was made grand Standard-Bearer of England by Edward IV. The Stradlings, again, traced their descent, in unbroken succession, from Sir William le Esterling, (which name became corrupted to Stradling,) one of the twelve Norman knights associated with Robert Fitzhamon, the cousin of William II. (Rufus), in the conquest of Glamorgan. As his share of the conquered district, Sir William le Esterling obtained the castle and manor of St. Donat’s, with other extensive possessions. Sir Thomas Stradling, the last of the name, continued to reside at St. Donat’s; but died, a childless man, at Montpellier, in France, on the 27th of September, 1738; and was buried at St. Donat’s on the 19th of March, 1739. David Mathew, Esq., of Llandaff, the father of Dorothy Morgan, was likewise the father of Brigadier-General Edward Mathews, and the grand-father of the well known Admiral Mathews, who was thus the first cousin of David Morgan. Admiral Mathews contested the county of Glamorgan with Sir Charles Kemys Tynte, of Cefen Mabley, and was elected by a majority of 47. The election was held at Cardiff, and commenced on the 2nd of January, 1744, the poll extending over _nine days_. Though possessed of no proof that such was the case, I strongly suspect that the father of David Morgan acquired Penygraig by his marriage to Dorothy Mathews. But I have not been able to learn whether he ever resided there, nor where his son was born, though the period of his birth must have been 1695, or 1696. His father, being the second son, would naturally have removed from Coed-y-gorres after his marriage; and it is probable that Penygraig became his residence. Where David was educated does not appear; but it is clear that he received a liberal education.
