Harold, the Last of the Saxon Kings Book X: The Sacrifice on the Altar by Edward Bulwer-lytton

It was the second day after that which assured him the allegiance of the thegns, that a message was brought to Harold from the Lady Aldyth. She was in Oxford, at a convent, with her young daughter by the Welch King; she prayed him to visit her. The Earl, whose active mind, abstaining from the intrigues around him, was delivered up to the thoughts, restless and feverish, which haunt the repose of all active minds, was not unwilling to escape awhile from himself. He went to Aldyth. The royal widow had laid by the signs of mourning; she was dressed with the usual stately and loose-robed splendour of Saxon matrons, and all the proud beauty of her youth was restored to her cheek. At her feet was that daughter who afterwards married the Fleance so familiar to us in Shakespeare, and became the ancestral mother of those Scottish kings who had passed, in pale shadows, across the eyes of Macbeth [216]; by the side of that child, Harold to his surprise saw the ever ominous face of Haco.

But proud as was Aldyth, all pride seemed humbled into woman's sweeter emotions at the sight of the Earl, and she was at first unable to command words to answer his greeting.
