I've seen her ad on tryst the past couple of months, is there any info? Thanks!

Her last name hints to Desi but I have a feeling that she's light black. Maybe not even that light too. Photo tinkering can do wonders nowadays.  

Some people think I'm of French descent because impposter ~ imposteur. Others think I'm of Spanish extraction because impposter ~ impostor. And a few think that impposter is an anglicanation of  the German Hochstapler. But then I point out that impposter is not my real name and that it derives from being an "impish poster" ~ "imp-poster" ~ impposter.

Her tryst ad does say that she identifies as "an exotic mixture of Afro-Indian heritage."

I can tell you that she is not East Indian.  

...and she might not be lying. The question is mate is she Indian as in Cherokee or Sioux? With the last name like Patel it must be Sioux. What do you think?

I don't know common Sioux or Cherokee names. But Desi (Deshi) definitely refers to Indian sub-continent Indians. http://en.wikipedia.org/wiki/Desi (See my old post about the movie "ABCD" = American Born Confused Deshi. Still waiting for the sequel "EFGH.")

Patel is, most often, a Gujarati name. Gujarat is on the Western coast of India, abutting the Arabian Sea. With modern migrations and intermarriage, her lineage might actually be back to East India, not West India. But someone else, Verr22, already posted that she isn't East Indian. Who knows?
