 Genealogical family history research is an important aspect of Latter-day Saint tradition, stemming from a doctrinal mandate for church members to research their family tree and perform vicarious ordinances for their ancestors.Church members believe the ordinances "seal" or link families together, with the ultimate goal being an unbroken chain back to Adam and Eve.Church members are able to do genealogical work in various family history centers throughout the world, usually located in LDS meetinghouses.
