Walter Liath de Burgh

Sir Walter Liath de Burgh was an Anglo-Irish noble, the eldest son of Sir William Liath de Burgh and Finola Ní Bhriain of Thomond. He is first recorded in 1326, when he and Sir Edmond de Burgh were named guardians of the peace and keepers of the late Earl of Ulster's lands in Connacht, Tipperary and Limerick.

He later quarrelled with the young Earl William Donn, who imprisoned him; Walter starved to death in the earl's castle in February 1332, a killing that led to the earl's own murder the following year.
