Mark Sydney Davis is the adopted son of entertainment legend Sammy Davis Jr. and Swedish actress May Britt. Born April 6, 1960, in Los Angeles, he was adopted at age three in 1963. Despite growing up in Hollywood’s spotlight, Mark chose a quiet life, working as a Costco photo clerk by 2015. A 2015 DNA test confirmed he wasn’t Sammy’s biological child, yet their bond remained unshakeable. Today, Mark lives in California, raising two sons and provingthat family is built on love, not genetics.
When Sammy Davis Jr. adopted Mark Sydney Davis in 1963, he welcomed a three-year-old boy into one of Hollywood’s most-watched families. The adoption made headlines—not just because Sammy was an entertainment icon, but because his interracial marriage to May Britt was still controversial in 1960s America.
Mark’s story isn’t about chasing fame. It’s about a man who lived alongside legends but deliberately stepped away from the spotlight. His life raises questions many adopted children face: What defines family? Can love matter more than biology?
Early Life in a Hollywood Household
Mark Sydney Davis entered the world on April 6, 1960, in Los Angeles. Three years later, his life changed forever when Sammy Davis Jr. and May Britt finalised his adoption on June 3, 1963.
The Davis home wasn’t ordinary. Frank Sinatra dropped by. Michael Jackson visited. Mark grew up watching his father rehearse dance routines and listening to conversations about civil rights and breaking racial barriers in entertainment.
But privilege came with pressure. Cameras followed the family everywhere. Their interracial household—a Black father, Swedish mother, and adopted children—challenged social norms during the Civil Rights era. Mark learned early that privacy was precious.
Growing Up With Famous Siblings
Mark wasn’t alone. He had three siblings:
- Tracey Hillevi Davis — Sammy and May’s biological daughter, born in 1961. She later became an author before passing away in November 2020.
- Jeff Nathaniel Davis — Another adopted son, sharing Mark’s experience of growing up in the Davis family.
- Manny Davis — Half-brother from Sammy’s third marriage to Altovise Gore, adopted in 1989.
These relationships shaped Mark’s understanding of family. Biology mattered less than the bonds they built through shared experiences—hotel room adventures, swimming pool jumps, and watching their father perform.
The Biological Father Question
For decades, speculation surrounded Mark’s parentage. Some documents listed Sammy Davis Jr. as his father. The ambiguity created lifelong questions.
In his final days in 1990, Sammy made a deathbed confession. He looked at Mark and said, “You are my son.” Those words ignited controversy and confusion that lasted 25 years.
The 2015 DNA Test Results
Mark and Tracey decided to end the speculation. They underwent DNA testing through Identity Match in 2015.
The results were definitive: Mark Sydney Davis was not Sammy’s biological child.
For some, this might have been devastating. For Mark, it clarified what he’d always known—real fatherhood isn’t about DNA. Sammy raised him. Loved him. Taught him. That made Sammy his father in every way that mattered.
Career Path: From Backstage to Behind the Counter
Mark’s professional life reflects his values. He didn’t pursue stardom. Instead, he worked behind the scenes.
Working With Sammy Davis Jr. in the 1980s
During the 1980s, Mark served as an assistant stage manager on his father’s U.S. tours. His responsibilities included:
- Preparing Sammy’s signature tap shoes before performances
- Setting up the whiskey glass prop for stage appearances
- Managing the autocue system that displayed lyrics
This work gave Mark rare access to his father’s world. He saw the discipline behind the glamour. The exhaustion after the shows. The dedication required for excellence.
These years strengthened their relationship. Sammy was often absent during Mark’s childhood, consumed by performances and tours. Working together created the connection they’d missed earlier.
The Costco Years
By 2015, Mark had left entertainment entirely. He took a job as a photo clerk at a Costco store near Hollywood, Los Angeles.
This decision shocked many. Why would the son of Sammy Davis Jr.—a man who earned millions—work retail?
Mark’s answer was simple: he valued peace over prestige. He’d witnessed fame’s toll on his father—the constant travel, the IRS debt problems, the pressure to always perform. Mark wanted stability. Privacy. Time with his own family.
The Costco job provided all three. No photographers. No interviews. Just honest work that paid the bills and let him go home to his sons each night.
Fatherhood: Breaking the Cycle
Mark Sydney Davis is the father of two sons: Ryan and Andrew (sometimes called Andy).
Parenting these boys became Mark’s most important work. He was determined to be present in ways his father couldn’t be.
Mark once told The Daily Mail: “They are the joy of my life, and I try to be the father to them that Sammy was not to me. Parenthood is not perfect, but my father and I never communicated. I want to be different with my sons.”
Lessons From an Absent Father
Sammy Davis Jr. loved his children. But his career demanded everything. He toured constantly, performed nightly, and rarely had time for school events or bedtime stories.
Mark felt that absence deeply. As an adult, he chose differently:
- He attends his sons’ activities
- He prioritises communication and listening
- He provides emotional support and physical presence
One touching detail: Ryan plays drums—just like his grandfather Sammy. The musical talent skipped a generation, connecting grandson to grandfather through rhythm and beat.
Views on Adoption and Identity
Mark’s experience shaped his perspective on adoption. He understands the questions adoptees face: Who are my biological parents? Why was I given up? Where do I belong?
His answer: family is built through daily acts of love. Adoption doesn’t make you less connected—it proves that parents choose to love you, which can be more powerful than accidental biology.
Life After Sammy: Carrying the Legacy Quietly
Sammy Davis Jr. died on May 16, 1990, from laryngeal cancer at age 64. He’d been diagnosed with throat cancer in September 1989, likely caused by decades of heavy smoking.
His death left Mark without his father figure at age 30. It also ended the complicated financial legacy Sammy left behind—approximately $15 million in debt despite earning over $50 million throughout his career.
Mark inherited memories, not money. But those memories shaped his values:
- Work matters more than wealth
- Privacy beats publicity
- Being present for family outweighs professional achievement
Current Life in California
Today, Mark Sydney Davis lives a deliberately low-profile life in California. At 65 years old (as of 2025), he focuses on:
- Raising his two sons with intention and care
- Supporting his mother, May Britt (now in her 90s)
- Maintaining relationships with surviving family members
- Staying out of the media spotlight
He’s been married three times, though details about his spouses remain private—exactly how Mark prefers it.
What Mark’s Story Teaches Us
Mark Sydney Davis represents something rare in Hollywood: someone who rejected fame despite having every reason to pursue it.
His father was Sammy Davis Jr.—a member of the Rat Pack, friend to Frank Sinatra, performer for presidents. Mark could have traded on that name his entire life.
Instead, he chose authenticity. He worked honest jobs. Raised his kids. Lived according to his own values.
The Real Meaning of Family
The DNA test proved Mark wasn’t biologically related to Sammy. But genetics don’t determine family. Time does. Experience does. Love does.
Sammy raised Mark. Protected him. Provided for him. Made him part of the Davis family story. That bond survived death and DNA tests.
Why Privacy Matters
Mark’s choice to work at Costco wasn’t a failure—it was freedom. He’d seen how fame consumed his father. The constant performances. The financial troubles. The inability to walk anywhere without recognition.
Mark chose differently. He wanted to be known by his sons, not strangers. To have relationships, not fans. To live fully, not publicly.
Understanding Mark’s Connection to Hollywood History
Mark’s life intersects with major cultural moments:
The Civil Rights Movement — His adoption occurred during the peak of civil rights activism. His parents’ interracial marriage (Sammy and May married in 1960) challenged societal norms.
The Rat Pack Era — He grew up surrounded by Frank Sinatra, Dean Martin, and other entertainment legends who defined 1960s Las Vegas culture.
Changing Attitudes About Adoption — His story reflects evolving views on adoption, biological vs. chosen family, and identity formation.

Final Thoughts

He didn’t. He chose a different measure of success: being present for his sons. Working honest jobs. Living privately and peacefully.
His story challenges our assumptions about fame, family, and what makes a life well-lived. Not everyone wants the spotlight. Not every child of a legend wants to be legendary.
Sometimes, the bravest choice is stepping away from what everyone expects and building the life that makes you whole.
Mark Sydney Davis did exactly that. He’s Sammy Davis Jr.’s son—not because of genetics, but because of 30 years of shared life, love, and lessons that DNA could never measure.
