Will they respect my wishes in my last will and testament?

I don’t want to cremated. Cremation goes against Islam. I want to give part of my stuff to my Flower Girl, but no-one knows Who She is, or where exactly She lives (I know the city, if She hasn’t moved). I would be embarrassed to have my body buried under the name that my parents gave me instead of the one I gave myself. I want the burial to be done with Islamic and Jewish rules, but doubt that will happen.

Will they respect my wishes in my last will and testament?
