The photos above  were both taken in New Orleans.  Although the one at left looks a lot like my great grandmother, I tend to think it must be her sister and the other would be her daughter.  I'm still not sure which sister lived in New Orleans.
The photos below are both taken in new York State, one at Oswego and the other at Suracuse.  They could be of the same woman and would likely be of Louisa Lauver Burrows (Burris) who is buried in New Jersey.
