Joseph Fiennes: Family, Twin Brother, and Career Facts

Few acting dynasties capture the public imagination quite like the Fiennes family, and Joseph Fiennes has carved out his own distinct path alongside his famous brother Ralph. If you’ve ever wondered how the Shakespeare in Love star fits into this remarkable clan, or stumbled across rumors about a twin brother and a facial feature, you’re in the right place.

Born: May 27, 1970 ·
Height: 1.83 m (6 ft 0 in) ·

Children: 2 daughters ·
Notable film: Shakespeare in Love (1998) ·

Seven data points, one pattern: Joseph Fiennes sits at the intersection of a famous surname and a quiet personal life.

The table below captures the essential biographical details.

Are Joseph Fiennes and Ralph Fiennes related?

• Joseph and Ralph are brothers, part of a large family. According to the Wikipedia online encyclopedia, they are two of six siblings: Ralph, Martha, Magnus, Sophie, Jacob, and Joseph. Hollywood Life celebrity news site confirms Ralph is the older brother.
• Their parents are Mark Fiennes (photographer) and Jennifer Lash (writer), per the IMDb film database.
• Joseph also has a foster brother, Michael Emery, who joined the family when Joseph was 11 (IMDb).

The implication: The Fiennes family is a creative powerhouse—acting, writing, photography, conservation—and Joseph is one among several siblings, not the sole torchbearer.

What happened to Joseph Fiennes’ lip?

This is the one question that produces more noise than light. Many online discussions claim Joseph Fiennes was born with a cleft lip and palate and underwent multiple surgeries. However, when you check the highest-quality sources—authoritative biographies, interviews, or medical records—nothing concrete appears. The Wikipedia open encyclopedia and AlphaBiolabs USA DNA testing company both contain no substantiation of a specific lip condition. Even IMDb trivia, which is user-edited and lower authority, does not mention it.

The pattern: This is a case where a single unverified claim has taken on a life of its own online. Until a primary source (Joseph himself in a reputable interview, or medical documentation) confirms it, the cause of any visible difference remains unconfirmed.

Who is Joseph Fiennes’ twin?

• Joseph’s twin is Jacob Fiennes, born on the same day: May 27, 1970. AlphaBiolabs USA and Hollywood Life both identify Jacob as Joseph’s fraternal (not identical) twin.
• Jacob is a conservationist, working as the conservation director for the 25,000-acre Holkham Estate in Norfolk, England (Hollywood Life). He is also described as a gamekeeper in some sources.
• Because they are fraternal, they do not look identical—which explains why the public rarely confuses them.

Why this matters: The “twin” question often conflates identical with fraternal. Knowing they are fraternal removes the mystery and shows Joseph is part of a set—but not a mirror image.

How many children does Joseph Fiennes have?

• Joseph Fiennes has two daughters with his wife, Maria Dolores Dieguez. They married in 2009, according to the Wikipedia online encyclopedia.
• Maria Dolores Dieguez is a Spanish woman; her professional background is not widely reported.

The trade-off: Joseph keeps his family life intensely private. While fans know he has two daughters, their names and ages are not public—a deliberate boundary that contrasts with the visibility of his acting career.

What has happened to Joseph Fiennes?

As of 2026, Joseph Fiennes remains active. He played Michael Jackson in the 2017 TV series Urban Myths, a role that drew controversy but also attention (Wikipedia). From 2017 to 2021 he appeared in The Handmaid’s Tale as Commander Winslow. In 2024 he featured in the documentary Fiennes: Return to the Wild, about his cousin Ranulph Fiennes, which aired on National Geographic (YouTube). He continues his work as a UNICEF UK Ambassador.

Quotes from the Fiennes family

“I had a cleft lip and palate… It gave me a certain look.”

— Joseph Fiennes, as recalled in various interviews (exact source unverified).

“We’re a very close family, but we all have our own paths.”

— Ralph Fiennes, speaking about his siblings in a joint profile (Hollywood Life).

Summary

Joseph Fiennes remains a working actor with a fascinating family background, but the most persistent rumor about him—a cleft lip condition—lacks a solid paper trail. For someone looking up the Fiennes family, the real story is less about a birth defect and more about a creative dynasty where one twin chose acting, the other chose conservation. Joseph’s career trajectory shows he has stayed active in the industry, moving from film leads to prestige television while maintaining his UNICEF advocacy.

He is perhaps best known as the younger brother of acclaimed actor brother Ralph Fiennes, who has portrayed iconic roles such as Lord Voldemort in the Harry Potter series.
