Our grandson, Jalen, 9, asked me the other day how to spell his father's middle name. I told him that it, "PIANHKI", had several spellings, which are: Pianhki, Pianhky, and the latest one, PIYE. I wrote those names down for him and explained where Nubia was in Africa, and what "dynasty" meant, since Piye founded the 25th. Grandkids can ask the darndest questions from out of nowhere, it seems. Be ready!
