by the United States Circuit Court for the Southern District of Ohio, McArthur v. Allen (1880)
“ Every one interested, if he choose to do so, may make himself a party to the record. Nothing is in question but the legal status of the will. That instrument is the res of the controversy, and in the absence of fraud all persons concerned, whether formally before the court as parties or not, are necessarily alike concluded by the verdict. “Substantially this is a proceeding in rem, and the court cannot take jurisdiction of the subject-matter by fractions. The will is indivisible, and the verdict of a jury establishes it as a whole or wholly sets it aside. ”
