To start off, I completely made up DiMango. The house names, the classes I added in, everything. WE DO NOT OWN THE HARRY POTTER SERIES. J.K. Rowling is the creator/author of the Harry Potter books and series. So, here's the History of DiMango School of Witchcraft and Wizardry:
DiMango was founded in 1975 by Thomas C. DiMango. It was in a small island in Hawaii, that only Wizards may see. He decided to build a school to teach his family. Little did he know, the school would soon become a fairly famous one. The first house, named Blinsagr, was named after his step-dad. The last name meant 'power' and 'wealth'. The second house, named Remeliius, was named after his mother's maiden name and his step-brother's name. His mother's maiden name was Remli, and his step-brothers last name was Melis. He combined the 2, forming the name Remeliius. By 1982, the school was a success. DiMango died in 1994, and the job was passed down to Devin L. James, DiMango's other brother-in law.
