Last Name Ruidiaz

What is the origin of the last name Ruidiaz?

The surname Ruidiaz has roots in Spanish language and culture. It is derived from a personal name, Ruiz, which is of Visigothic origin. "Ruiz" itself comes from the Germanic elements "hruod" (famous) and "ric" (powerful or ruler). Over time, the personal name Ruiz was Latinized as Rufius, and when Spanish surnames were adopted during the later Middle Ages, it evolved into the modern spelling of Ruidiaz. The "diaz" part of the surname typically signifies a son of a particular individual with the surname Díaz, which is also of Visigothic origin, derived from Theudis (a Visigoth king who reigned in Hispania from 473 to 526 AD).
