John E. (1825 - 1919) and Eliza (1829 - 1878) Marshall
These are charcoal on canvas portraits of the couple we believe to be
the parents of Charles E. Marshall (no photo available) and the grand
parents of Jenny Marshall King.
While the portraits have suffered some of the ravages of time, they
are an interesting study of the subjects, done (I suspect) by a
master portrait maker. Click on either of the links, and then
enlarge the image, and the details fairly jump out at you.
