Susannah Beck Crist

A photo of Susannah Beck Crist, mother of Margaret Crist Eaton, my grandmother:

Described, by my father, as a sweet little woman who lived in a log cabin in Revenge. She did not speak English; only German. I have had this picture for many years and only recently traced her ancestry I would like to know her connection (parents; Laurence Beck (1798-1854, b. in Wurtemburg, Germany) and Mary Ann Roberson (some say Robinson), one of 11 children...with Jacob Beck and his brothers who came from the same location, settled in Lancaster, OH and founded the Lutheran Church therein. Any other pictures???

Was it taken in Fairfield County OH?
