I rather like Brontë, since it reminds me of the sisters
Charlotte,
Emily and
Anne Brontë. I love their novels.
And I don't find Brontë any harsher than
Bridget or
Brianna. I like it much more than ln-as-fn like
Madison,
McKenzie,
Taylor,
Hunter etc.
Though I'm afraid the spelling would be butchered in USA; Americans don't seem to use accent marks.
