Hello, I am African American. According to my geneology, my great grandfather and great grandmother were partially white, I'm not sure what percentage. I definately don't know where the thal came from because my mother and my father have the trait. My sister who is 11 months younger also has it although I was the sicker child when we were little. I also have never meet anyone else with Thal , at least until I found this website. Glad I found it!!!
