According to Leslyn, Bella's mother was the favorite prostitute of Lord Robert Baratheon at the Peach when he hid in Stoney Sept during Robert's Rebellion. Bella is named after the Battle of the Bells, which occurred when Lord Jon Connington attacked the town in search of the future king.
A Storm of Swords
Arya Stark and Gendry meet Bella when they pass through Stoney Sept with the brotherhood without banners and stay at the Peach. Ignorant that Gendry is also a bastard of the late King Robert, Bella flirts with him, but he declines her advances. She then flirts instead with Jack-Be-Lucky.
