William Burke, Lord of Bealatury, Irish noble and soldier, fl. 1580s-1616. Burke was a member of the Burke family of Clanricarde, in what is now County Galway. He was one of five brothers who left Ireland to enrol in Spanish service in the late 1580s. They were in Ireland in time to participate in the Nine Years' War (Ireland). William accompanied Donal Cam O'Sullivan Beare on his march north in 1603. He appears to have gone to Spain in the years afterwards. William Burke signed himself Lord of Bealatury in Spanish documents of 1616.
