Well,  I wouldn't have picked them as the some person in a line up I don't think - definitely same period of dress though!!   

There is one of the photos which looks similar I think - in reverse.  In the second last link.     

Interesting links . . . but no further along the trail of my lady - unless they kept one of Olive's unknown people . . . and anyway only Katherine's name is showing if the square frame were in place.    Hmmm very tricky.

You can just see the shadow of the frame (which I didn't receive with this photo.) in this attachment.

It's actually very like the woman in the film clip - look at the nose and eyes 

What you need to find is why the photo, taken by a famous photographer got into the collection that you have now acquired.

only Katherine's name is showing if the square frame were in place.

It's most likely because of the size of the frame they used rather than any significance of covering a name

Yes - highly likely.
