Edmond Butler, 3rd/13th Baron Dunboyne

Edmond Butler, 3rd/13th Baron Dunboyne (1595–1640) was an Anglo-Irish nobleman of the early seventeenth century. His short life was full of violence and disputes over the Dunboyne inheritance. His father was murdered when Edmond was a small child, and Edmond, as an adult, was forced to defend a lengthy lawsuit brought by his uncle, who sought to disinherit him. In 1627, he killed his cousin James Prendergast in a quarrel over a disputed inheritance. For this crime, he was tried by his peers for manslaughter, but was acquitted.
