Baby Parker was born in a cabin to Brigitte and Mr. Parker. His mother, Brigitte, bled to death after giving birth to him.

Baby Parker’s mother is Brigitte and his father presumed to be Mr. Parker. Based on these assumptions, and the assumptions of paternity of these other characters, he also is half-sibling of Miss Parker and Mr. Lyle. Miss Parker, at least claims him as family and cares about his well-being enough to attempt to protect him from Raines whom she thought had ulterior motives when Raines gave Baby Parker treatment with a gas to loosen his lungs so that Baby Parker would not suffer the same fate as Raines, so he claimed.

After the events of Island of the Haunted we discover that if Baby Parker is the son of Mr. Parker and Brigitte, he is not biologically related to Miss Parker or Mr. Lyle.

There is some speculation that Baby Parker could actually be Mr. Lyle’s son.
