Named after a former Chief Secretary to Ireland William Eden, who asked John Beresford to name a street or a square after him if their combined plans for the improvement of Dublin ever came into being. In a letter to Beresford he wrote: "If our great plans should ever go into execution for the improvement of Dublin, I beg that you will contrive to edge my name into some street or into some square, opening to a bridge, the bank or the four courts."
