Creating Indian- Guyanese girl

I’m writing a story about an Indian- Guyanese girl in New York. Can anyone help me create multiple girl characters please. Also maybe little tips about the culture. (I know the basics) but if anyone has anything I might not want to miss would be great.

What exactly are you trying to look for? Are looking at how to create the character or are you looking for clues about the Indo-Guyanese culture?
