tin type photo of Sarah

A well dressed woman seated. She has dark hair in a bonnet or shawl that appears to be from the mid to early 1800's. The picture is not in very good condition. I touched it up some with Photoshop to remove some defects. It could be Buchanan, Davies, Sorenson, Jacobson, Anderson, Dutson, Lovell. All the families settled in Utah, though this may have been taken before coming to Utah.

I was told that this picture is a tin type. It is on a heavy fabric or leathery material. On the back, in pencil, is the name Sarah. I am not sure what side of my family it comes from, though it could be Sarah Davies from Wales.
