Photograph of a Young Woman IDed on Reverse as Capt. McKehrey, perhaps Salvation Army; by a Lewiston, Maine studio

Photograph of a young woman identified on the reverse as Capt. McKehrey, although I'm not sure I have interpreted the surname correctly.  The photograph was taken by the Hammond Brothers studio of Lewiston, Maine.

She may have been a captain in the Salvation Army.

 If you have a theory as to her identity, please leave a comment for the benefit of other researchers.
