Marmaduke Thweng, 1st Baron Thweng

[3] The son of Sir Marmaduke Thweng of Kilton and his wife Lucy de Brus.

Thweng managed to fight his way back across the bridge and he thus became the only knight of all those on the far side of the river to survive the battle.

Following the rout, Thweng with William FitzWarin were appointed castellans of Stirling Castle by the English leader John de Warenne, 6th Earl of Surrey.

[5] At the Battle of Bannockburn in 1314, however, after the English defeat, Sir Marmaduke apparently made no attempt to escape.

Robert recognised Sir Marmaduke and released him and Ralph de Monthermer, also captured, both without ransom, but not without first entertaining them at table.
