Barry was the lover of John Wilmot, 2nd Earl of Rochester--one of Charles II's closest friends. Their story is the focus of a current production of The Libertine at the Royal Haymarket Theatre in London. Though contemporaries apparently regarded Barry as "the ugliest Woman" in real life, they promulgated she was "the finest Woman in the World upon the Stage." (A Comparison Between the Two Stages, 1702).
Charles Macklin (1690-1797), was a prolific Irish actor and playwright, who, yes, lived to the remarkable age of 106. He most often performed at Drury Lane Theatre, especially in his most famous role of "Shylock" in Shakespeare's The Merchant of Venice.
In 1735 he accidentally killed a fellow actor, Thomas Hallam in a fight over a wig, but appears to have gotten away with only a fine.
