You have to restore the entire Library with Time Machine. So locate the library at a date just before this happened and restore. If you have enough room to keep both versions of the library I would do so till you've confirmed that the restored version has all of your photos.

Thanks OT. That's what I have done and am now comparing the libraries to see which one is the Keeper! Take care, always grateful for your help, Judy
