Whenever suit is brought under the provisions of sections twenty to twenty-seven, inclusive, of this chapter to quiet the title to real estate, no one whose actual or possible title, claim, or lien, is sought to be removed or construed, and whose name appears of record in some public office in connection therewith, may be made defendant in accordance with the preceding sections, except under his proper name or the name appearing in such record, nor shall his unknown heirs, devisees, legatees and assigns be included as defendants therein, unless fifteen years have elapsed since the recording of such title, claim or lien. When any one against whom proceedings under sections twenty to twenty-seven, inclusive, of this chapter might otherwise be brought is known to be dead, and some of the persons who might claim under him and their places of residence are known, such of them as are known shall be named as defendants and brought before the court in the manner provided by law, and all others who might claim under such deceased person may be included as unknown defendants.25
