Question: In what year was the royal house's name change? Passage:The programme explores the lives of King George V and Queen Mary, and their attempts at modernising the British Monarchy in response to the massive social changes during and following World War I. The first episode recalls how, fearing anti-German sentiment, the royal house name was changed by King George from the House of Saxe-Coburg and Gotha to the House of Windsor. The series also examines the personal lives of the couple, delving into their relationships with their children, and with each other. The marriage between George and Mary was an arranged marriage, occurring only because Prince Albert Victor, George's brother and Mary's original fiancé, died from influenza. George V is presented in the series as a disciplinarian, who strictly punished his children, but was known to be much more loving to his granddaughter, Queen Elizabeth II.

Question: What other voice work was done by the person who voiced Ed Grimley's pet rat?  Passage:Episodes of the show often featured Ed Grimley in several adventures, which start out as mundane, but turn very surreal and cartoonish, interspersed with science lessons from The Amazing Gustav Brothers, Roger and Emil, and a live-action segment with a "scary story" titled The Count Floyd Show presented as a show-within-a-show by Grimley's favorite television host, SCTV's Count Floyd (played by SCTV cast member Joe Flaherty). Grimley's fellow cartoon characters included Grimley's landlord Leo Freebus (voiced by Jonathan Winters), Leo's wife Deidre (voiced by Andrea Martin), his ditzy, amateur actress neighbor Ms. Malone (voiced by Catherine O'Hara; a female character by the name of Ms. Malone did appear on an SNL version of an Ed Grimley sketch on the season ten episode hosted by Alex Karras, but Ms. Malone was played by that episode's musical guest Tina Turner), and her little brother Wendell (voiced by Danny Cooksey). Ed owns a goldfish named Moby and a clever pet rat named Sheldon (voiced by Frank Welker). At the end of each episode, Ed would write in his diary about what happened in his day.
