Ptolemy John Williams is the first child for the actress and her director husband
Gretchen Mol and her husband, director Tod Williams, are parents of a son.
Ptolemy John Williams was born Sept. 10, the actress’s rep says.
Mol, 34, who starred in 2005’s The Notorious Betty Page, most recently appeared in the Russell Crowe western 3:10 to Yuma and the comedy The Ten.
At The Ten‘s premiere last July, she said she and Williams, 38, who directed The Door in the Floor, had recently moved back to New York. “I wanted to have a New York baby,” she said.
