As an heiress Margaret brought to her husband an income of about £200 a year from manors in Herefordshire, Nottinghamshire and Warwickshire.

In 1429 her husband's career at court gained him a knighthood at the coronation of Henry VI and she became Lady Willoughby.

[2] Her husband's riches increased, he now owned the important manor of Middleton in Warwickshire and a large quantity of silver which had been a prize of battle taken by Thomas Beaumont siegneur de Basqueville.

After exactly a year of widowhood, Ralph, Lord Cromwell, and Sir John Fortescue, made a judgement concerning the will.

[1] She died in 1492 and she left her partial control of the manor of Middleton to Sir Henry Willoughby, her grandson[4] whose career flourished despite his part in the abduction of Jane Statham and forcible marriage to his brother Richard, which is considered to have triggered a change to the law in England to make abduction of a property-owning woman a felony.
