Sixth-plate ambrotype in a wood and leather case and brass double-elliptical mat and preserver of Anna Kate Davis (later Knight) (1856-1951), taken circa 1857 by an unidentified photographer. This photograph was taken while Anna Kate and her parents Charles R. Davis (1823-1900) and Betsey Jones Wood Davis (1827-1905) were still living in Illinois. In 1870, Anna Kate and her family moved to Denver where she met and married Stephen Knight (1856-1935). Stephen and Anna Kate had three children: Rodger D. Knight (1883-1941), Stephen J. Knight (1887-1943) and Evelyn Knight (1891-1982). This ambrotype seems to be taken at the same time as accession number 83.4.456 due to Anna Kate wearing the same dress. From the Evelyn Knight collection.
