In Sep 1389 the Scrope vs Grosvenor Case was brought to the Court of Chivalry. Up to that time two families, Scrope and Grosvenor, had been using the armorial Scrope Arms: Azure, a bend or.

Several hundred witnesses were called including John of Gaunt 1st Duke Lancaster (age 49), Geoffrey Chaucer (age 46) and John Savile of Shelley and Golcar (age 64).

On 03 Sep 1386 Owain ap Gruffudd "Glyndŵr" Mathrafal Prince Powys (age 27) gave evidence at the Church of John the Baptist, Chester [Map].

The Court decided in favour of Scrope.

Neither party was happy with the decision so King Richard II (age 22) was called upon to give his personal verdict.

On 27 May 1390 he confirmed that Grosvenor could not bear the undifferenced arms.

As a consequence of the case the Grosvenor has for many years used the name Bendor for horses and nicknames.
