Quite likely them, seems to fit.
Interesting jewel Jane is wearing at her neck...looks like a cameo.
Don't you just love the tablecloth hanging up as a backdrop...I think awkward little touches like that make early photos very precious.
Just a little note for your family history in general...in census returns Certain Young Women Of A Dubious Repute, shall we say, often called themselves "dressmakers"...

I hasten to add, of course, that there were many, many actual dressmakers about

In fact, before ready-made clothing came along there was likely a dressmaker on every street. Some clothes were constructed with gussets sewn into the seams, so the dress could be let out as the wearer grew. One social convention that kept dressmakers busy was the mourning customs. Since a woman who lost a mate or other family member was obliged to go into mourning immediately, she usually trotted her entire wardrobe into the garden and simmered every item in horrible black dye. Then when the mourning period was over, she had to replace every dress. In addition to that, dress was a statement of social status and every woman of any means liked to keep up with the latest trend.
So your Jane was likely a busy woman
