Duplicate individuals can make a family tree confusing and may affect relationships, reports, and genealogy research. Before combining records, create a complete backup of your tree. FTM Support can help users understand how to review duplicate individuals and determine whether two records actually represent the same person. Compare names, birth dates, locations, spouses, parents, sources, notes, and photographs before making changes. Never merge people simply because their names look similar. FTM Support guidance can be useful when users are uncertain about the correct records to combine or need help recovering from an unwanted change. Careful source checking is especially important when researching common names. Keeping detailed citations and notes can make identifying genuine duplicates much easier over time.
