Mystery Couple

I scanned this image from an actual tintype. The tintype was found in a box of old photos which my Georgia grandmother owned. Her name was Rilla Bray Leaird and she lived in Athens, Georgia.

Since the tintype came from my Georgia grandmother we assume the photo was taken in Georgia and we assume it is a picture of her relatives. No one in the picture has been identified. There is no writing on it. My grandmother is no longer alive to identify the couple. Are these relatives of my grandmother? Surnames in her and her husband's genealogy include Bray, McLeaird/Leard, Hill,Davis, and Hansford.
