Did Mary Lincoln Suffer from Pernicious Anemia?

Reignette, I believe that is a close-up of Mary in a photo that was taken when Native American chiefs visited the White House in March of 1863. I think this photo was taken in the White House conservatory, and Mary is in the rear at the far right. John Nicolay is in the rear-center.

Lloyd Ostendorf writes, "Mrs. Lincoln appears older than she does in some other pictures taken that year, possibly because of the harsh side lighting on her face." The photo has a "Brady 1862" imprint, but the Native Americans visited in 1863. Offhand I have no explanation for that discrepancy.
