Unknown Elegant Lady

Woman appears to be between 18 and 25 years old. Photo belonged to James H. and Mary Anna Ballentine Powell, Newark, NJ. Woman in photo most likely came from NY or NJ during the 1800's. Possible family names are Powell, Hamilton, Ballentine, Pridham, Grout, Hart, Randell, or Moran.

Do you know who this woman is? If so, please contact me. I'm trying to return photo to her family.
