Thomas McLean

Thomas McLean was the father of Tristan McLean, whom he had Piper with Aphrodite.

History
Piper called him Grandpa Tom, and she said he died of lung cancer a few years before she left to Camp Half-Blood. He believed in Cherokee animal spirits. She and her father spent one night camping out in front of his house in Oklahoma. That night she and her father discussed Cherokee and Greek legends about the stars.

He was the one that decided to call her Piper, as he said that she would have the greatest voice in the whole family because of her loud screaming as a baby. He had also said that she would learn how to sing the toughest Cherokee songs, like The Snake Song. He told Piper's dad stories about how the stars were formed and that the Greek myths were a bunch of bull.
