The name Honoria was the name of two Agatha Christie characters: Honoria Waynflete in Murder is East and Honoria Bullstrode in Cat Amongst the Pidgeons.
My husband's name is Honorio, since they don't have this site I will comment under the female version. I personally like the name, and the meaning, but my husband grew up in Mexico, where the name isn't very common. He never liked his name, but when I look at it I think of the word Honor. He also has trouble with English speakers pronouncing it right, since in Spanish the H is silent.
Two sort of famous bearers for this name who are both minor characters in the Harry Potter series of books are Honoria Nutcombe who founded the Society for the Reformation of Hags, and was J. K. Rowling's Wizard of the Month for August 2004, and also: Honoria Dumbledore - Albus' maiden aunt. And that is all. But also I might add I think this name is really lovely, and I think it's an awful shame it's not used more often.
