The David Sampson Seals Family

I was going through a envolope full of pictures  and found copies of pictures my grandmother Merle Sophia Hepler Windham had made of her grandfather's brothers  that look like there were taken around the time of the American Civil War. They are nice looking men. Her grandfather  David Sampson Seals had four brothers  Noel, John W, Oliver, William J.  and two sisters Mary and Elizabeth. On the back of the copies my grandmother wrote Sampson Seals brothers, uncles to Birdie M. Seals. I wish she had left more information like where she got the copies? Who had the orginals?   My grandmother Merle Hepler Windham started some family history books for each of her children, grandchildren and great -grand children thats where some of this information was going to but didn't make it. In one envolope she has of copies of a picture of  Nancy Ann Graham Seals ( born abt 1806 in White County, Tennessee  died abt 1899 in Van Buren County, Tennessee) the mother of David Sampson Seals. Not a great picture but still better than nothing and I would have to say I'm glad to have it. Looks like it was taken 1880's -1890's.
