Sandra, first back-up your data. Then go to the INDIVIDUAL screen. Make sure it is showing in alphabetical order. Do this by clicking near FULL NAME in the title bar. Then look for two references of the name of the child in question. Highlight one of the names. Then click on FIND (the binoculars) in the task bar. This will bring up the FIND INDIVIDUAL screen, with the child highlighted. In the screen at the right you will see details of this child's family. Check both children this way and determine which one is the duplicate/incorrect entry. Delete the incorrect one. Just check the parents too, to make sure you have them correctly entered.
