Presuming, kind reader, that you may have inferred that sweet Ellen Armstrong, as the Earl was wont to term her, was his daughter, we must now undeceive you, stating that such was not the case.  The history of her connection with the earl was as follows: 

As he returned home from an exciting session of the House of Peers, late on a cold night in December, 1703, (nearly 14 years previous to the date of the commencement of our story,) he was greatly surprised, upon entering the drawing-room of his elegant mansion, to find his wife busily employed in fondling and carressing a beautiful infant, apparently not more than two or three weeks old.

‘What does this all mean, Lady Armstrong?’ exclaimed the earl, as soon as his surprise had in a measure subsided.

‘Listen, and I will tell you,’ replied the lady, ’About two hours ago, the street-door bell rang violently, which caused me to despatch a serving maid to ascertain from whom this loud summons proceeded.  She immediately went to the door and opened it, but found no one there.  Upon turning back again into the entry, her ears were assailed by the faint cries of this dear babe, whom she soon after discovered, esconced very comfortably in a large wicker basket.  This with its contents was soon conveyed to my presence, and upon removing the infant from its place of rest, I found this note attached to its dress.’

So saying, Lady Armstrong handed a letter to her husband, which he opened, and then read from it as follows: 

    ’To the Right Honorable George Armstrong, Earl of
    Derwentwater.

Sir:  The writer of this, being well aware that your matrimonial union still remains unblest with children, would earnestly entreat you to adopt the infant which this accompanies, as your own.  If you should see fit to comply with my request, you can rest assured that no pecuniary means shall be wanting, to insure to her, if she lives, all the educational and other accomplishments fitting to your rank, and that to which at some future day she herself, will be entitled.  A draft for the necessary funds will be punctually placed at your disposal at the commencement of each year, until those who have a right, shall claim her at your hands.  If you do right by her, you will gain the approval of a good conscience; if not, you will feel the vengeance of a parent’s heart.  But I can explain no farther.  Adieu, yours, &c.,

    Montmorenci.’

After having read the above singular epistle, the earl held a long consultation with his amiable wife, which resulted in their concluding to comply with the request of the mysterious writer, to adopt the poor foundling as their own daughter, and at the same time, they determined never to reveal to her the secret of her strange advent amongst them.  In accordance with these resolutions a suitable nurse for the young infant was immediately procured, and when it had reached a proper age, it was baptized by the name of Ellen Armstrong.
