Cabinet Photos of Margaret Little and Margaret Little Purcell; Albany and Chestertown, New York studios

1884 Cabinet photograph of Margaret Little, taken by a studio at Albany, New York, whose name I can't make out.  This photograph came with a companion photograph of a younger woman named Margaret Little Purcell, taken by a studio at Chestertown, New York, which is a bit north of Albany.  Here is the reverse of the photograph of Margaret Little, showing the identification:

Photograph of Margaret Little Purcell, "Aunt Mag", taken by J. F. Holley, Chestertown, New York.  

There is  the written name "Stella" on the reverse in addition to the identification.

I'd be interested in knowing how these two women are related: mother/daughter; aunt/niece, etc.  If you have any knowledge of a Margaret Little and/or Margaret Little Purcell in the Albany, New York area, please leave a comment in the comments box or contact me directly.

Thanks for stopping by!
