You are not clear as to exactly what you want to delete. Do you want this info not to show on the report? OR do you want to delete the 2nd wife? To delete the 2nd wife, simply delete the record (go to the record and then hit SHIFT+F9.
If you don't want it to show on the report, that may be more difficult since they ARE a part of the family. If you send it to a word processor, though, you may be able to delete the two people (or words) that you do not want.
