Matthew van Lewen

Matthew van Lewen is an infant born in the rich yet haunted van Lewen family. His father wanted to protect him from a ghost that was haunting his family and so abandoned him.

Phoebe found him at the police station and brought him home.

After the ghost was vanquished, he was returned to his family, with only his mother left with him.
