Romilda (died 611), was a Duchess consort of Friuli by marriage to Duke Gisulf II of Friuli. She served as regent of Friuli in 611, during the invasion of the Pannonian Avars. Romilda was reportedly the daughter of Garibald I of Bavaria. She married Gisulf II of Friuli, and became the mother of the sons Tasso, Kakko, Radoald and Grimoald, and the daughters Appa and Geila (or Gaila), married to the King of the Alemanni (uncertain) and the Prince of the Bavarians, probably Garibald II of Bavaria.
Romilda Pantaleoni (1847 – 20 May 1917) was an Italian soprano who had a prolific opera career in Italy during the 1870s and 1880s. She sang a wide repertoire that encompassed bel canto roles, Italian and French grand opera, verismo operas, and the German operas of Richard Wagner.
Romilda is the name of the aggressive girl who goes to any lengths to make Harry Potter go out with her in JK Rowling's Harry Potter series. She appears the first time in book 6. She's pretty but stuck-up.
