his installment in the principality of Wales, as is apparent in Mathew
Paris, which he would never have done, it his wi••e had been the sole
sister and heir of David; for by the raising of Griffith to the throne of
Wales, he should not only depose David, but also most indiscreetly ex∣clude
himselfe from being heir apparent to the principality of Wales,
and next to rule after David, who had no issue. Secondly, the Lord
Mortimer, after the death of prince David, made no claime to the
principality, which in no w••se he would have omitted, if he had been
his heir apparent, and the king of Englands nephew, as you pretend,
who for the recovery of his right would minister unto him sufficient
aid both in men and money. But this neglect infallibly denoteth, that
Gwlades with her posterity was not the heir of David, seeing that Le∣oline
held that peaceably with the consent of the King. And in an
old book written above 200 years ago, I found the pedegree of Richard
Duke of York, father of king Edward the 4. wherein the Dukes de∣scent
is first brought to the Mortimers by Anne his Mother, and from
the Mortimers to the Princes of Wales by the said Gwlades, as being
sister and heir of Griffith and not of David, even thus: Leolinus fuit
princeps Walliae, & pater Gladys ddu, haeres suus fuit Griffinus princeps
Walliae, qui habuit quatuor filios, Lew••linum (ille fuit ultimus princeps
Walliae,) Owinnm, David, & Rodri, qui decesserunt sine haered bus: ideo re∣vertamur
ad Gladys Dhu, quam Radulphus Mortimer duxit in uxorem.
Lewelyn was Prince of Wales, and the father of Glaays ddû, his heir
was Griffith Prince of Wales, who had 4. sons, viz. Lewelyn the last
Prince of Wales, Owen, David, and Rodri, who dyed without heirs;
therefore let us come back again to Gladys ddu, whom Ralph Mortimer
married. Hereby it appeareth that Griffith was L••welyn ap Jorwerth's
son & heir, & therefore born in Wedlock, & that his four sons leaving
no Heirs (as that Author saith,) the right of the principality descen∣ded
to the posterity of Gwladus, which directly proveth she was sister
of the whole bloud to Griffith, and not to David, of whom the Author
maketh no mention at all; accounting him and his sisters (some of
whose posterity live at this day) no better then Bastards. Thirdly our
ancient books of pedegrees do with one consent affirme that the children
of Leoline ap Jor: were Griffith and Gwlades dhu, whose mother was
Tanglwyst the daughter of Lhowarch goch of Ros: David Prince of
