No, Jeffrey Epstein didn't have a baby boy, his brother says

• Jeffrey Epstein was congratulated for having "a baby boy" in a 2011 email.
• Mark Epstein, Jeffrey's brother, says he did not have any kids.
• The message, included in the DOJ's Epstein files, was signed "Sarah" and refers to "The Duke."

Jeffrey Epstein did not have any children, despite what an email in just-released documents suggested, his brother told Business Insider.

"No, Jeff didn't have any kids," Mark Epstein said Monday. "If Jeff had a kid, I think I would have known."

The denial comes in reaction to a set of messages included in the latest cache of Epstein files issued by the US Department of Justice.

The messages, sent in September 2011, are signed "Sarah xx" and reference "The Duke." They appear to have been sent through BlackBerry Messenger.

The sender's name and email address were redacted by the Justice Department. The BBC and other British media outlets have reported that they may have come from Sarah Ferguson, the ex-wife of the former Prince Andrew, who also held the title Duke of York.

"Don't know if you are still on this bbm but heard from The Duke that you have had a baby boy," one message says. "Even though you never kept in touch, I still am here with love, friendship and congratualtions on your baby boy."

A follow-up message sent the same day accused Epstein of befriending her "to get to Andrew."

"You have disappeared. I did not even know you were having a baby," the message said. "It was sooooo crystal clear to me that you were only friends with me to get to Andrew. And that really hurt me deeeply. More than you will know."

A representative for Ferguson didn't immediately respond to a request for comment.

The former prince is now known as Andrew Mountbatten-Windsor. He relinquished his royal titles last year, around the release of a posthumous memoir from Virginia Giuffre, who accused him and Epstein of sexual abuse. In 2022, the former royal had also settled a civil lawsuit brought by Giuffre.

Another message from "Sarah," dated January 2010, expressed intense gratitude for Epstein.

"You are a legend. I really don't have the words to describe, my love, gratitude for your generosity and kindness," Sarah wrote. "Xx I am at your service . Just marry me."

Aside from the "baby boy" message, the vast public corpus of emails and other documents released so far has made no reference to Epstein having a child.
