Names do NOT reliably indicate nationality or ethnic background.
True story from just this morning... my little neighborhood store, Swami's (yes) run by mom and pop. Mom is from India..Dad from Pakistan. I affectionately calll him Swami. When we got to talking this morning, I finally learned his real name, which is Robert Fernandes. Huh? Yep. As he explained.. his ancestor went from Portugal to Pakistan during WW1.
Names are just labels.
