The sound of the English letter "B" is "ΜΠ" in Greek. Therefore "Brandon" is spelled as "Μπράντον".I assume the intonation is on the first syllable (Bra), therefore the accent mark is on "Μπρά".In the same way "book" would be spelled "μπουκ" and not "βουκ".The sound of the English letter "V" is "Β" in Greek. This may be the source of confusion.This has already been answered here: https://learn-greek-online.com/ask-greek/1236/brandon-in-greek
