In family search lite, I want to have the ability to generate 1..n number of relative related to my starting a certain year to a year. I will then work this list to see if there are any missing ordinance work and request the work.
You can use your descendancy view pedigree to see who is missing ordinances. If you open each arrow that is pointing right, so that it shows you who is attached in generations below, you will see all of the temples ready for temple work. It is confusing to track, and familysearch frequently reloads the descendant tree if you walk away or log in to some other things, so do it a small section at a time. Be sure to address any duplicates or data errors before reserving the work.
