From Michael Altschul, *A Baronial Family in Medieval England: The
Clares,1217-1314*, Baltimore MD (Johns Hopkins Press) 1965:
"Joan of Acre, on the other hand [as compared to GILBERT's first wife
Alice de Lusignan], was a remarkably active woman in the dozen years
following the Red Earl's death. By the terms of the marriage agreement
of 1290, the entire inheritance was enfeoffed jointly on GILBERT and
Joan. This meant that it would not be possible for her father EDWARD I
to grant her only a third of the estates and control the rest himself
during the long minority of her son Gilbert. Joan was thus sole mistress
of the inheritance, and she controlled it with marked ability. In 1297,
much to EDWARD's displeasure, she secretly married an otherwise
obscure knight in her 'familia', Ralph de Monthermer (d. 1325).
Joan of Acre died in April, 1307, but during her tenure of the
inheritance important modifications were introduced in its
administrative structure. After Isabella de Fortibus, dowager countess
of Devon and Aumale (1262-93), Countess Joan stands as perhaps the
best example in thirteenth century English history of the ability of a
widow to run the estates and otherwise manage the complex affairs of a
great comital house." ( pp. 38-39).
"The marriage between GILBERT and Joan had long been planned and long
delayed. Joan was EDWARD's second surviving daughter, born when her
father was still on crusade in 1272. In 1276 Rudolf of Hapsburg, the
German Emperor, had prosed a marriage between the girl and his son
Hartmann. Negotiations were conducted in 1277 and 1278, but the whole
project had to be abandoned when Hartmann was accidentally killed in
December, 1281. In May, 1283, THE KING agreed to a marrige between
his daughter and EARL GILBERT. THE EARL had been separated from Alice
de Lusignan since 1271, but a formal annulment was now required, and
the marriage was finally dissolved in May, 1285. The king and the earl
still had to wait for a papal dispensation for the new marriage, and it
was only forthcoming in November, 1289.
GILBERT DE CLARE 6TH EARL OF GLOUCESTER, "THE RED" and Joan of
Acre had the following children:
1.) Gilbert de Clare 7th Earl of Gloucester, who died in 1314."
2.) Eleanor de Clare.
3.) MARGARET DE CLARE.
4.) Elizabeth de Clare.
