SOCIETY DIVORCE ECHO.
RENUNCIATION OF SURNAME.
By the following curious advertisement a society divorce which created considerable interest in England a few years ago is recalled:—
"I, Muriel Ellen Fane, of Beauford Gardens, in the County of London, wife of Cecil Francis William Fane, formerly wife of Onslow Powell Traherne, late of Greenstreet, Park Lane, in the same county, hereby gives public notice as follows:— Whereas I have the custody of Jack Osborne Traherne, who was born on the 25th day of August, 1900, and of Angela Maude Traherne, who was born on the 17th day of October, 1901, and who are issue of the marriage of the said Onslow Powell Traherne and myself. Now I hereby give public notice on behalf of the said issue or children of the said marriage, and of myself, as their guardian, that they, the said children, shall and will renounce, reliquish, and abandon as from the date hereof the said surname of Traherne, and shall and will assume and adopt henceforth tho surname Fane, and shall and will on all occasions whatsoever subscribe the name of Fane instead of tho name of Traherne. — MURIEL ELLEN FANE."
Mr. Cecil Francis William Fane married in 1880 Lady Augusta Rous, eldest daughter of the late Earl of Stradbroke, and sister'of the present peer. That marriage was dissolved in 1904 on the petition of Lady Augusta, who has two sons. Mr. Traherne had also obtained a divorce three years earlier.
