Meet Theresa D'Antonio, Author of The Last Don's Mistress

Some stories are told loudly, in headlines and court records. Others are kept quiet for decades. Theresa D'Antonio writes the quiet ones.

Theresa D'Antonio is a debut author with Trumpet Publishing House. Her work sits where memoir, history and human intimacy meet, in the rooms that official accounts never entered.

The Last Don's Mistress: The Private Life of Joe Bonanno, Sr. is her first full length work. It is an adult title, and it does not soften what it finds. Rather than another chronicle of organized crime, it looks at the private life beside it, and at the woman whose account has not been heard in full until now.

Who Is Theresa D’Antonio?

Before she was anyone’s mistress, anyone’s widow, or anyone’s “Zio’s Theresa,” she was a nineteen-year-old girl leaving Alexandria, Egypt, with a suitcase and a brother, headed for a country she’d never seen.

That’s not the version of Theresa D’Antonio most people will meet first. Most people will meet her through the headline: the woman who spent twenty-five years with Joseph Bonanno, Sr., the last surviving boss of the American Mafia’s founding generation, and kept his secrets, his letters, and her own journal of it all until now. That story is real, and it’s the one told in her debut memoir, The Last Don’s Mistress: The Private Life and Times of Joe Bonanno, Sr. But it’s the second half of her life, not the whole of it. To understand how she ended up there, at “Zio’s” side in a quiet Tucson house, it helps to start decades earlier, in Egypt.

A Childhood in Alexandria

Theresa was born Theresa Kupelian, into a family of Armenian heritage, in Alexandria. Her father’s people had fled Russia during the 1905 revolution with little more than gold coins sewn into their clothes, and rebuilt a merchant business from nothing in Egypt. It was a comfortable, tightly bound family life, until history intervened again: when the Nasser regime took over Egypt in the early 1960s, Theresa and her brother immigrated to Montreal, leaving everything else behind.

Flight Attendant, Wife, Mother, Widow, Twice

In Montreal, her fluent French helped her get a job with Air Canada as a flight attendant. It was on one of those flights that she met an American passenger, T. J. Vorachek. They married, she moved with him to Tucson, Arizona, and they had a son, Aaron. The marriage didn’t last; it ended in divorce.

What came next reads like the setup to a much longer story than a paragraph should hold. A co-worker introduced Theresa to her own brother, Lawrence “Larry” D’Antonio, a Tucson attorney. Theresa and Larry married. Through Larry, she came to know his close friend and client: Joseph Bonanno, Sr., long retired from his life as a Mafia boss, and Bonanno’s wife, Fay, who became one of Theresa’s dearest friends. Then, within the space of a few years, Larry died of cancer. Theresa was widowed. Not long after, Fay died too, after a long illness.

Two people who already loved each other’s spouses were suddenly grieving the same kind of loss, together.

Twenty-Five Years With “Zio”

What began as companionship between two widowed friends became, over time, something else entirely: a relationship that lasted twenty-five years, between a woman in her prime and a man forty years her senior. To the rest of the world, he remained Joseph Bonanno, Sr. Inside Theresa’s own family, he became “Zio,” Italian for uncle, the name he gave himself the moment he started introducing her that way to everyone he knew.

She was there while he wrote his own memoir, A Man of Honor. She was there for the ordinary, unglamorous texture of his old age: the meals, the arguments, the letters he answered by hand, the stories he only ever told her. And she kept a record of it as it happened, not from memory decades later, in journals and letters and photographs she held onto long after he died in Tucson on May 11, 2002, at ninety-seven.

Why She Waited to Tell It

Theresa didn’t publish a word of this for more than twenty years. By her own account, the decision arrived somewhere over Arizona, on a flight home after a difficult visit, replaying “all the good and bad times we had been through together” until it felt, in her words, “like a movie playing in my head.” That flight is where The Last Don’s Mistress began, even though it would take her another three decades to actually complete and find the right publisher. Her son, Aaron, who grew up alongside all of it, writes in the book’s foreword that he watched his mother keep that journal for years, and can vouch for it firsthand.

It’s a unique kind of debut: a first book from a woman in her later years, about a relationship most of the world never knew existed, built from an archive she was quietly assembling the entire time she was living it. That’s who Theresa D’Antonio is: not just the woman who loved Joe Bonanno, but the one patient enough, and private enough, to wait until for the right moment to reveal her story.

The Last Don’s Mistress: The Private Life and Times of Joe Bonanno, Sr. is Theresa D’Antonio’s debut memoir, published by Trumpet Publishing House.
