Most people who search for Mark Sydney Davis are really trying to answer one specific question — is he Sammy Davis Jr.’s biological son or adopted son? The answer is more layered than a simple yes or no. There is a DNA test, a reported confession from Sammy himself, and a birth certificate that seemed to point in a different direction. All of it together tells a complicated family story worth understanding properly.
This article covers what is confirmed about Mark’s birth and adoption, the family he grew up in, the paternity question and what DNA testing revealed, and what little is publicly known about his adult life today.
Who Mark Sydney Davis Is
Mark Sydney Davis — also listed in some records as Mark Davis or Mark Sidney Davis — was born on April 6, 1960, in Los Angeles, California. He is widely described as the adopted son of entertainer Sammy Davis Jr. and Swedish-American actress May Britt.
His adoption was finalized around June 3, 1963, when he was approximately three years old. Some reports, including an Inside Edition segment, describe him as being adopted at around age two, which aligns closely with the timeline. A birth certificate listing Sammy and May Britt as his parents does exist, but that reflects his adoptive legal status rather than confirmed biological parentage.
MyHeritage’s genealogical records describe him plainly as the “adopted son of Swedish American actress May Britt and American entertainer Sammy Davis Jr.” That framing is the most accurate starting point for understanding who he is.
The Family He Was Raised In
Mark grew up in one of the most recognizable households in American entertainment. His father, Sammy Davis Jr., was a singer, dancer, comedian, and actor who became one of the most celebrated performers of the 20th century. He was a core member of the Rat Pack alongside Frank Sinatra and Dean Martin, and songs like “Candy Man” and “Mr. Bojangles” made him a household name worldwide.
His mother, May Britt — born May Britt Ringquist in Sweden — was a working actress before and during her marriage to Sammy. The two married in 1960, the same year Mark was born. Their interracial marriage was deeply controversial at the time. Both faced public backlash and professional consequences. Sammy lost film work. May Britt stepped away from acting almost entirely. It was a high-profile family living under significant social pressure during one of the most turbulent periods in American civil rights history.
Mark had several siblings growing up:
- Tracey Hillevi Davis — Sammy’s only confirmed biological child with May Britt. She was born in 1961 and passed away on November 2, 2020.
- Jeff Nathaniel Davis — another child adopted by Sammy and May Britt.
- Manny Davis — Mark’s half-brother, born during Sammy’s later marriage to actress and dancer Altovise Joanne Gore Davis.
That family makeup — two adopted children, one biological child, and a half-sibling from a later marriage — reflects how complex Sammy’s personal life was behind the public persona.
Sammy Davis Jr.’s Claim and the DNA Test
For decades, the public record described Mark simply as Sammy’s adopted son. But later in life, according to accounts that emerged publicly, Sammy reportedly told Mark something different. He told him that he was not just adopted — he was his biological son.
Mark also reportedly found a birth certificate listing Sammy as his father, which seemed to support what Sammy had told him. That combination — a parent’s direct statement and a document — would be enough to make anyone question the adoption story they had grown up with.
To get a clearer answer, Mark and his sister Tracey agreed to take a DNA sibling test through a service called Identity Match. The result was definitive. There was no DNA match. The test concluded that Mark and Tracey do not share a common biological parent.
An Inside Edition segment covering the story put it plainly: “It’s not a match…the DNA test results in this case show that the alleged siblings do not share a common biological parent.” That result means Mark is not Sammy Davis Jr.’s biological child. His status as an adopted son stands as the factually supported conclusion.
The tension between Sammy’s reported statement and the DNA outcome is real, and both are part of the public record. Sammy may have believed what he told Mark. Or there may have been other circumstances involved that are not fully documented. What the science shows, however, is that Mark and Tracey are not biological siblings — and that is the clearest evidence available.
It is also worth noting that Inside Edition described Mark at the time of the DNA story as working as a photo clerk at Costco. That detail says something meaningful about the kind of life he has lived — quiet, private, and far from the spotlight of his famous father’s world.
Mark’s Adult Life Outside the Spotlight
Mark has lived a largely private life as an adult. There is no public record of him pursuing a career in entertainment. He has not been a public figure in his own right, and most coverage of him traces back to either his connection to Sammy Davis Jr. or the DNA test story.
Some reports — primarily citing a Daily Mail article — suggest that Mark has been married three times and has two sons named Ryan and Andrew Davis. However, these details come from a single secondary source and have not been corroborated by multiple independent outlets. They are worth mentioning but should be understood as reported rather than firmly confirmed.
Beyond that, reliable public information about his current life, career, or personal circumstances is limited. That is not unusual for someone in his position. Being the adopted child of a famous parent does not make someone a public figure by default, and Mark appears to have chosen to step away from whatever attention his family name could have brought him.
How Mark Fits Into Sammy Davis Jr.’s Broader Legacy
Sammy Davis Jr. died on May 16, 1990, from throat cancer. He left behind a complicated personal legacy — enormous artistic achievement, a groundbreaking career that pushed against racial barriers, and a private life marked by financial struggles, addiction, and multiple marriages.
Mark’s story fits into that legacy as a reminder that famous families are rarely as simple as they appear from the outside. Sammy and May Britt chose to adopt children at a time when their interracial marriage was already making them targets of public criticism. That decision reflected something real about who they were as people, regardless of biology.
Genealogy platforms like MyHeritage list Mark as part of the Davis family tree — as an adopted son. That is how family history databases handle adoptive relationships, and in many ways it captures what matters most. He was raised in that family. He was legally Sammy’s son. And that relationship, DNA aside, defined his childhood and identity.

Final Thoughts
Mark Sydney Davis is not a celebrity. He is a private person whose life became a matter of public curiosity largely because of who his father was. What is confirmed is straightforward: he was born in 1960 in Los Angeles, adopted by Sammy Davis Jr. and May Britt around age two or three, raised alongside siblings in one of the most famous households in American entertainment, and later found through DNA testing that he and his sister Tracey did not share biological parents.
Sammy reportedly told him otherwise. That reported moment is part of the story too. But the scientific evidence points in one direction — Mark is Sammy’s adopted son, not his biological child.
Beyond that, he has lived his life quietly, and that is worth respecting. Not every child of a famous person needs to become famous themselves. Sometimes the most honest thing a profile can do is acknowledge what is known, be clear about what is not, and leave the rest alone.
