I know shes American and Caucasian but... Looking at her I sense she is mixed with either American Indian or South American somewhere down the line? Maybe it just me? She does have broad cheeks (the ones on her face ;) ) and very dark brown eyes. Oh did I forget to mention she is very beautiful?

She is lovely. I don't know her being of another nationality, though.

Lisa is indeed part Native American. One of her grandmothers (or great-grandmothers) was native American (Cherokee, I believe). If I recall correctly, she also has Irish & German in her background.
