1610 – 1623) was an actor in English Renaissance theatre, a member of Shakespeare's company the King's Men.
A "William Eglestone" was married to an Ann Jacob on 20 February 1603 at St. Saviour's in Southwark; this might (or might not) have been the actor.
The man who definitely was the actor was with the King's Men in 1610 and 1611; he was part of the cast of their productions of Jonson's The Alchemist (1610) and Catiline (1611).
Yet Ecclestone returned to the King's Men later in 1613, and was in their production of Fletcher's Bonduca that was performed around that time.
Some commentators have speculated that Ecclestone might have been the "W. E." who wrote commendatory verses for the first quarto of Fletcher's The Wild Goose Chase in 1652; but the three-decade gap between 1623 and 1652 is problematic.
