All
Thanks so much
So - I'm consolidating - woman in her late teens/early 20's and photo prpobably taken early 1880's. However, due to shape and backing this is most likely a reprint which was done in the late 1880's - mid 1890's and quite possibly the sitter had passed away at the time of the reprint.
Once again, thank you all so much for sharing your knowledge.
