In ?1349, Sir Thomas Trussell was possibly granted a Uncertain licence to crenellate (Warmingham)

There is insufficient evidence to be certain about this possible licence to crenellate.

I can't find in the CPR or CChR. In 1349 William Trussell held the manor. The only Thomas Trussel to hold the manor dates to 3-20 Edw VI (1460-80)

Significant later source are;

• Emery, Anthony, 2000, Greater Medieval Houses Vol2 (Cambridge) p477
