The great-grandfather of Petyr Baelish was a Braavosi sellsword that came into the Vale of Arryn at the service of Lord Corbray. His line was continued by his son, who became a hedge knight and took the head of the Titan of Braavos as his sigil. According to semi-canon sources, the son also acquired a small bit of land and a keep on the smallest of the Fingers. His first name is unknown.
