In 1335 she was married to John Segrave, 4th Baron Segrave, and proceeded to have four children - two sons and two daughters - by him. In 1350, she sought a divorce on the ground that they had been contracted in marriage (in other words betrothed) before she was of marriageable age, and that she had never consented to cohabit with him. She made known her intention of traveling to the continent in order to plead personally with the Pope for a divorce. King Edward III prohibited her from leaving England, but she set off incognito anyway, having taken care to obtain a safe conduct from the King of France.
