The ancestor chart, descendants chart, and search results all depend on the Settings you choose to determine whether a particular person is considered "complete" or is missing some information.

To customize how leaf searches for missing information, you can click on the button and this will show you the following form:

  • "Check Only Basic Information" will check only whether a person has a complete birth event (date and place) or death event (date and place).
  • "Check Detailed Information" will check for birth, death and marriage events, plus whether the person has parents, a spouse, and children.
