From Wikipedia - Margaret de Clare, Lady Badlesmere :

Margaret de Clare (c.1 April 1287 - 22 October 1333/ 3 January 1334) was a Norman -Irish noblewoman and the wife of Bartholomew de Badlesmere, 1st Lord Badlesmere .[1]In 1321, she was arrested and imprisoned in the Tower of London for refusing Isabella of France , Queen consort of King Edward II , admittance to Leeds Castle of which her husband, Lord Badlesmere, was castellan .

Family
Margaret was born at Bunratty Castle in Thomond , Ireland on or about 1 April 1287, the youngest child of Thomas de Clare , Lord of Thomond and Juliana FitzGerald of Offaly . Her paternal grandparents were Richard de Clare, 6th Earl of Hertford, 2nd Earl of Gloucester and Maud de Lacy . Her maternal grandparents were Maurice FitzGerald, 3rd Lord of Offaly and Maud de Prendergast (born 17 March 1243), daughter of Gerald de Prendergast and a de Burgh daughter whose first name is not known. Margaret's maternal ancestors included Brian Boru , Dermot McMurrough , and Maud de Braose .

Margaret had an elder sister, Maud and two brothers, Richard de Clare, 1st Lord Clare , who was killed at the Battle of Dysert O'Dea in 1318, and Gilbert de Clare, Lord of Thomond.[2]

On 29 August 1287, when she was almost five months of age, her father died. Her mother married her second husband, Nicholas Avenel sometime afterwards.

Margaret was co-heiress to her nephew Thomas de Clare, son of her brother Richard, by which she inherited the manors of Plashes in Standon, Hertfordshire and lands in Thomond, Limerick and Cork in 1321 upon the death of Thomas.[3]

Marriages
Before 1303, she married firstly, Gilbert de Umfraville, son of Gilbert de Umphraville, Earl of Angus, and Elizabeth Comyn. Upon their marriage, the Earl of Angus granted Gilbert and Margaret the manors of Hambleton and Market Overton. When Gilbert died childless, sometime before 1307, the manors passed to Margaret.
Sometime before 30 June 1308, she married secondly, Bartholomew de Badlesmere, 1st Lord Badlesmere ,(1275 -14 April 1322 ) an English baron and Governor of Bristol Castle, by whom she had five children.[4] She was styled as Lady Badlesmere on 26 October 1309 , and henceforth known by that title.[5]

Leeds Castle
Lord Badlesmere was appointed castellan of the Royal Castle of Leeds in Kent , by Thomas, 2nd Earl of Lancaster , Regent of King Edward II . In October 1321, the queen consort Isabella of France went on a pilgrimage to the shrine of St. Thomas at Canterbury . She decided to break her journey by stopping at Leeds Castle, which was given to her as part of her dowry[6] Bartholomew was away at the time leaving Margaret in charge of the castle. Due to her dislike of Isabella as well as her own belligerent character, she refused the Queen admittance, and subsequently ordered her archers to fire upon Queen Isabella when she approached the outer barbican . When King Edward heard of the treatment meted out to his consort by Margaret, he sent an expeditionary force to the castle. After a successful assault of the castle, with the King's troops using ballistas , the defenders surrendered, and Margaret was seized and sent to the Tower of London .[7]
As a result of Margaret's arrest, Lord Badlesmere joined Lancaster's rebellion and fought in the Battle of Boroughbridge on 16 March 1322. He was arrested and afterward hanged for treason on 14 April 1322. Margaret remained imprisoned in the Tower until 3 November 1322.[2] She was released from the Tower, due to the successful mediation, on her behalf, of her son-in-law William de Ros. She retired to the convent house of the Minorite Sisters, outside Aldgate .[8]

In 1328, her son Giles obtained a reversal of his father's attainder and succeeded to the barony as the 2nd Baron Badlesmere.
Margaret died between 22 October 1333 and 3 January 1334.[9]
