The first game of proto-Royals was played in Granada Hills, California, by Devin and Liam Carroll in about 1973. Devin was home from college, and Liam was a high school student.
The rules of Royals were developed over the next couple of years by the Carroll Brothers: Brian, Devin, Forrest, and Liam.
Devin developed Alliance Royals in 2010.
Marriage Royals is brand new in 2013. So far, no games have been played.
