Painted by Lydia Castelhun Solari (1869-1957, daughter of Johann Christoph Castelhun & Augusta Kruegen), this painting entitled Peach Blossom is believed to be of her aunt Lydia Pauline Roetter Castelhun (1846-1926, daughter of Paulus Roetter) when she was approximately 20 years old and was known as the Belle of St. Louis.  I'm not convinced about this identity, though, and am open to other thoughts about who this so-called Peach Blossom may have been.
