Hi all, 

I recently came across some impeccable sources for 2 separate Richard Druesdales [not Trusdales!] in England as follows:

Richard de Druesdale - served in France (Battles of Crecy & Calais) in Edward III's army in the years 1346/7

https://archive.org/stream/CrecyAndCalais/Cr%C3%A9cy_and_Calais_djv...

Also one Richard Druesdale who is mentioned at Stafford debtors court in 1416 - barber [or barber surgeon]

Translation from Latin:

William Markys of Bristol, merchant, by his attorney offered himself on the fourth day towards Richard Druesdale of Stafford, in the County of Stafford, Barber, and Richard, Ferrour or Smith, of Stafford in the County of Stafford, Ferrour [Farrier or Ferrour: Horse Shoer - often referred to as a Blacksmith], concerning a plea that either of them should render to the same (William) thirty pounds which to the same (William) they owe and unjustly detain &c And they did not come..

It's possible that these 2 Drysdales (Druesdales) are father & son and may also be errant relatives of the Dryfesdale Barony viz. Sir Humphrey de Bois, of Dryfesdale, who was slain at Lochmaben in 1333 etc.

Best regards
