The picture below was taken by Rick on a Ghost Tour on July 31, 2005.  There appears to be the figure of a woman at the back of the Officers' Quarters.   She seems to be wearing a long dark dress. 
I've posted the original version (although it's been lightened up), as well as one with the figure in a red circle.  You can choose which one you can see better.

The following pictures were taken by Kelley at a Ghost Tour at Fort George on Aug. 18, 2005.
These are close-ups of a picture taken in the Barracks, in the area of the marriage quarters.  Note:  While Mike was telling the stories in the Barracks, the curtain on the right -hand side of the marriage quarters could be seen moving.
In the first two pictures, faces can be seen inside the circles.  In the third picture, there appears to be a face inside the purple orb.
