Garrett Flowers is a bastard son of Garth the Gross.
A Feast for Crows
As part of the deal to bring Garrett's father Garth to King's Landing as the new master of coin, Garrett was to be named to the Gold Cloaks. However, Cersei Lannister quickly inserted Lord Gyles Rosby in as master of coin. It is unknown whether Garrett still joined the Gold Cloaks.
