Bronte (Brontë) comes from the Greek brontē, meaning "thunder." The Brontë surname was adopted by the Reverend Patrick Brontë (born Patrick Brunty) in homage to Lord Nelson's title Duke of Bronté.
The Brontë sisters — Charlotte, Emily, and Anne — were three of the greatest English novelists. Today Bronte is rising as a girls' name — particularly in Australia and the UK.
Bronte 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 Bronte reduce to 2, The Peacemaker. This is a traditional interpretive system, not a factual claim about the name.
