I have learned that those who engage in family history research and then perform the temple ordinance work for those whose names they have found will know the additional joy of receiving both halves of the blessing.
Furthermore, the dead are anxiously waiting for the Latter-day Saints to search out their names and then go into the temples to officiate in their behalf, that they may be liberated from their prison house in the spirit world. All of us should find joy in this magnificent labor of love. - Howard W. Hunter, “A Temple-Motivated People,” Ensign, February 1995
