who posed for the Statue of Liberty?

Hi Stumped! Actually, we had this question in this forum just a few days ago. Go here to get the answer:

I had thought she was a compilation of women, including the artists mother, but the question was posed to me as "what American" posed for the S.o.L.? so I answered Pocahontis, the "native American" said to be amongst the many woman making up Lady Liberty. The questioner hasn't responded back yet as to whether I'm correct.
