- Duplicating temple ordinances for ancestors is inefficient and wastes precious resources, as each set of ordinances requires about 8 hours of effort. - Green arrows indicating temple work is needed on FamilySearch are not always accurate. Careful research is required to verify relationships and avoid duplicating ordinances that have already been completed. - Sources like birth, marriage, and death records should be found and attached to an individual's profile to prove their identities and relationships before completing temple ordinances. Census records alone are not sufficient.
