I always think this woman and I bear some resemblance, although it could just be the soft round face and double chin, lol. I think she is the mother of our “all boy” child previously shown. She has obviously curly hair that was difficult to tame, glasses and small earrings. She even has a strand of pearls that sit very close to her neck – that would bother me. From what I can see of her dress, this is an 1890s photograph.
The photography studio was Hardy & Van Arnam of Troy NY. They appear on the list of most prolific photographers during the CdV era. In their little town, one of their competitors was Zeph. F. Magill, who we saw previously and who was involved in some sort of scandal involving a fraud suspect. It appears that they might have won the competition being as Magill does not appear on that list of prolific photographers. They opened their studio in the early 1870s.
