She was a daughter and co-heiress of Roger Mortimer, 1st Earl of March and Joan de Geneville, Baroness Geneville.

Baron Camoys: The barony of Camoys was created twice.  From 26 November 1313 to 1 April 1335 Ralph de Camoys (d.1336) was summoned to Parliament by writ, and is thereby held to have become Baron Camoys of the first creation.  Ralph de Camoys (d.1336) married firstly, Margaret de Brewes, daughter of William de Brewes, 1st Lord Brewes (d.1291), and secondly, Elizabeth le Despenser, daughter of Hugh le Despenser, 1st Earl of Winchester (executed 27 October 1326).

Hundred Years' War (1415–53): The Lancastrian War was the third phase of the Anglo-French Hundred Years' War.  It lasted from 1415, when Henry V of England invaded Normandy, to 1453 when the English lost Bordeaux.  It followed a long period of peace from the end of the Caroline War in 1389.  The phase was named after the House of Lancaster, the ruling house of the Kingdom of England, to which Henry V belonged.  After the invasion of 1419, Henry V and, after his death, his brother John of Lancaster, Duke of Bedford, brought the English to the height of their power in France, with an English king crowned in Paris.  However, by that time, with charismatic leaders such as Joan of Arc and La Hire, and with England losing its main allies, strong French counterattacks had started to win back all English continental territories, except the Pale of Calais (which was only captured in 1558).  Charles VII of France was crowned in Notre-Dame de Reims in 1429.  The Battle of Castillon (1453) was the last battle of the Hundred Years' War, but France and England remained formally at war until the Treaty of Picquigny in 1475.  English, and later British, monarchs would continue to nominally claim the French throne until 1801, though they would never again seriously pursue it.

Elizabeth Mortimer: Elizabeth Mortimer, Baroness Camoys (12 February 1371 – 20 April 1417) was an English noblewoman, the granddaughter of Lionel of Antwerp, 1st Duke of Clarence, and great-granddaughter of King Edward III.

She is represented as 'Kate, Lady Percy,' in Shakespeare's "Henry IV, Part 1", and briefly again as 'Widow Percy' in "Henry IV, Part 2".

Thomas de Thomon was the author of Old Saint Petersburg Stock Exchange and Rostral Columns on the spit of Vasilievsky Island in Saint Petersburg and the first building of the Odessa Theatre, destroyed by fire in 1873.
