Mortimer's chief care was to add office to office, and estate to
estate, in order that he might establish his house as supreme over all
Wales and its march. Besides his own enormous inheritance, he ruled
over Ludlow and Meath in the right of his wife, Joan of Joinville, the
heiress of the Lacys. He had inherited Chirk and the other lands of his
uncle, the sometime justice of Wales, who had died in Edward II.'s
prison; and he procured for himself a grant of his uncle's old office
for life, so that, while as justice of Wales he lorded it over the
principality, as head of the Mortimers he could dominate the whole
march. To complete his ascendency in the march became his great
ambition. He obtained the custody of Glamorgan, the stronghold of his
sometime rival, Hugh Despenser the younger. To this were added Oswestry
and Clun, the Fitzalan march in western Shropshire, forfeited to the

palatine franchises over Trim, Meath, and Louth, along with the custody
of the estates of the infant Earl of Kildare, the chief of the Leinster
Geraldines. He extended his connexions by marrying his seven daughters
to the heads of great families, and where possible to men of marcher
houses. He soon numbered among his sons-in-law the representatives of
the Charltons of Powys, the Hastingses of Abergavenny, now the chief
heirs of Aymer of Pembroke, the Audleys of the Shropshire march, the
Beauchamps of Warwick, the Berkeleys, the Grandisons, and the Braoses.
Anxious to extend his dignity as well as his power, he procured his
nomination as Earl of the March of Wales, "a title," says a chronicler,
"hitherto unheard of in England". As earl of the march and justice of
the principality, he ruled the lands west of the Severn with little
less than regal sway. His banquets, his tournaments, his pious
