there was no publicly available information confirming the identity of Owen Elliot's father. Owen Elliot is the daughter of Cass Elliot, who was famously known as Mama Cass from the singing group The Mamas & The Papas. Throughout her life, Cass Elliot did not publicly disclose the identity of Owen's father, and Owen has maintained her privacy on the matter as well.
It's important to respect individuals' privacy, especially regarding sensitive personal matters like family relationships. As a result, unless there have been updates or public statements made by Owen Elliot herself since my last knowledge update, the information about her father remains private and unconfirmed.
