Assuming the ambient light is low, you will need a long shutter speed for it to be visible in the photo.Th OP must have been shooting in low light.
@Op forget the barn, and go outside instead and just use a reflector, it will look much better than someone using a non-directional hard flash, especially when they don't know what they are doing with it.
Then you can expose the scene the way you know how to, but you should also learn how to shoot manual as well, as a backup, because then you wouldn't of had this issue, as you would have slowed the shutter, opened the aperture, and increased the ISO if needed.
So below are my rough guidelines/advice for your senior shoot.
1) Get a big reflector that your wife can aim and hold for you during the shoot.
2) Use a fast lens, a fast prime would be ideal, and shoot it at about F2 to get some nice bokeh, will need to use a fast shutter speed.
3) Learn at least 5 classic senior poses so that you are confident directing the subject.
