Duplicates
The Duplicates tool compares all of your member records and identifies those that show strong similarity across name and address information. This allows you to easily find and merge duplicates. This also allows you to easily identify family members (e.g., spouses) that can be connected to one another via the Edit Person screen (Relationships tab).
A higher score (100) indicates a very strong match while a lower score indicates a weaker match. If you are reviewing all potential duplicates, a good approach is to sort the Score column from highest to lowest and start with the matches with the highest scores first.
