All your wifes contacts are on your google account.. So your going to want to export them from google first.
Log into gmail, go to contacts, click more, click export.
Now export your wifes contacts to a file.
Then, follow these steps to restore your old contacts.
Once your contacts are restored again. The next time you sync, make sure that its not set so that the phone overwrites whats already stored on google.. You want to merge, not overwrite.
