      Note: The above death date "1 Aug 1359" in Brittany doesn't agree wit h anyone else including MCS itself in line 33-7. It turns out that Mar gery's 3rd husband John Avenel died in that place at that time. I am s ure it is an error.
      William de Ros, 3rd Baron Ros, was summoned to parliament from 20 Nove mber, 1317, to 12 September, 1342. This nobleman, in the 5th Edward I I (1312), was one of the commissioners appointed to negotiate peace wi th Robert Bruce, King of Scotland, about which time he came to an agre ement with the king regarding the castle of Werke, which he then excha nged with the crown for other lands.
