Why do members of The Church of Jesus Christ of Latter-day Saints trace their family history and do genealogical research?

The Church of Jesus Christ of Latter-day Saints emphasizes the importance of family relationships and believes that families can be united in the most sacred of all human relationshipsas husband and wife and as parents and childrenin a way not limited by death. Through priesthood authority from God, marriages are performed in temples. These marriages can continue throughout this life and for all eternity. In addition, children are "sealed" to their parents, meaning that their relationship to their parents will continue even after death. In order to give these same blessings to their deceased ancestors, Church members seek information about their ancestors to be able to perform marriages and sealings on their behalf. These ancestors may then choose to accept these sacred rites.  more
