1866(?) Queen Marie of Hanover and her daughter Mary by Wilhelm von Kaulbach (Schloß Marienburg)
Queen Marie of Hanover is portrayed here by von Kaulbach with her youngest daughter, Pricess Marie.
Queen Marie (1818-1907) had a daughter named Marie (1849-1904) who never married. This portrait could, therefore, be from around 1854. Marie's Subalbum, including a picture of this pair, is here.
