Honoria is the Latin feminine of Honorius — from honor. Justa Grata Honoria (c. 418-455) was the Roman princess, sister of Emperor Valentinian III, who in 450 CE sent her ring to Attila the Hun proposing marriage to escape her unwanted betrothal — triggering Attila's invasion of Gaul.
Her plea is one of the most consequential love letters in history.
Honoria does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.
In Pythagorean numerology the letters of Honoria reduce to 8, The Visionary. This is a traditional interpretive system, not a factual claim about the name.
