A woman who had resigned her home and infant children in order to avoid the worry of a husband's neglect or brutality, would be expected to return to her father's home; but this princess, it is alleged, first made good her retreat to France, and then, still apprehensive of discovery, notwithstanding the fact of the burial of her supposed remains, embarked for the United States, and settled in Louisiana. There she met a French sergeant who had formerly been in St. Petersburg, and all unregardful of her royal birth, married him, and bore him a daughter. In 1752, this _ci devant_ princess, accompanied by her French husband, visited Paris, and as she was walking in the Tuileries was seen and recognized, after all those years of change, by Marshal Saxe, who, however, gallantly promised not to betray her secret, and kindly procured a commission for her husband in the Isle of Bourbon, whither the strangely assorted couple went. Having lost her second husband and her child, the doubly bereaved princess returned to Paris in 1754, in the company of a negress. Getting into difficulties, in consequence of the East India Company refusing the bills she had brought with her in her husband's name, through her inability to prove herself to have been his wife, she took the opportunity of revealing her real rank to a gentleman who had known her in the Isle of Bourbon and, consequently, was induced to offer her his assistance. Soon after this wonderful revelation the _soi disant_ princess disappeared, but it was supposed that she had retired to the court of her nephew, the Duke of Brunswick. The King of France, it was averred, had long known the whole circumstances, and had even enjoined the Governor of the Isle of Bourbon to pay her the honours due to her rank. He also, it is said, sent an account of the discovery in his own handwriting to Maria Theresa, the Empress, who immediately wrote to the supposed princess, her aunt, and, doubtless, thinking a woman who had abandoned one husband and family would not be more particular over the next, advised her to quit her present husband and child, whom the King of France promised to provide for, and come and reside in Vienna. This female claimant seems to have utterly disappeared after the bill transaction in Paris, but her story, told in a dozen different ways, may be read in the histories and memoirs of the last century. THE FALSE PETER THE THIRD OF RUSSIA. A.D. 1773. The history of Russia has already furnished our records with some remarkable cases of pseudo royalty in the tragic stories of the Demetriuses and others, the suspicious circumstances so frequently attendant upon the death of members of the royal family of the Romanoffs having, doubtless, been the means of engendering such impostures as herein detailed. Yet the mystery surrounding the death of Peter the Third was not very dense, scarcely any one doubting that he was murdered at the instigation of his consort, Catherine the Second.
