Rachel Grate, Camilla Bell, Brenda Grate, ...Is Rodrigo Santoro ...

I read in the imdb that Rachel Grate is half American & half Brasilian, and so is her sister, Brenda Grate.
Does anyone know of any other actresses or actors born in the U.S.A. that have one American parent and one Brasilian parent? I'm very curious to know. Is Rodrigo Santoro half American or is he full brasilian?. Where was he born?

Here is my list of imdb actors that are half American and half Brasilian, have dual citzenship, and speak fluent English and fluent Brasilian Portuguese, if you know any imdb actors that fit this category, would you please add them
to my list? Thank you!!/ Obrigado!!!


Here is my list:

Rachel Grate
Brenda Grate
Camilla Bell


(This are the names i have in mind right now. I'll think of some more later)
