“You are my son” carried a lasting weight for Mark Sydney Davis. He recalled Sammy Davis Jr. saying those words near the end of his life in 1990. Mark later wondered whether the sentence meant more than the adoptive relationship everyone knew. I find that question central to his public story, but it should not eclipse a simpler truth: he was Sammy and May Britt’s son regardless of what later testing revealed about biology.
Mark was adopted by the couple in 1963. April 6, 1960, is commonly given as his birth date, with Los Angeles as the birthplace, although those details are not independently established by a vital record here. If the date is correct, he turned 66 in April 2026.
Sammy Davis Jr. and May Britt
Sammy Davis Jr. and May Britt married on November 13, 1960. Their interracial marriage drew racist hostility during a period when such marriages remained illegal in many American states. Mark entered a household already exposed to an unusual level of public attention.
Sammy was a singer, dancer, actor, and Rat Pack performer. May, born Maj-Britt Wilkens on March 22, 1934, was a Swedish actress. Her marriage affected her film career, including the loss of a studio contract.
They had a biological daughter, Tracey, in 1961, adopted Mark in 1963, and adopted Jeff in 1965. The marriage ended in divorce in 1968. I would not turn those dates into a detailed account of Mark’s private childhood; they establish the family framework, not every experience within it.
Adoption and a Birth Certificate
Accounts differ slightly over Mark’s age when adopted. Some call him about two, while a commonly listed June 3, 1963, finalization would make him three if the April 1960 birth date is correct. I keep that discrepancy visible rather than pretend the chronology is perfectly settled.
Mark said he saw a birth certificate in 2013 naming Sammy as his father and May as his mother. He also said he knew May was not the woman who had given birth to him. The certificate therefore did not settle the question of biological parentage in the way he hoped.
People who knew Sammy had also told Mark that Sammy was his biological father. Combined with the remembered deathbed sentence, those comments encouraged him to seek an answer. I would present that as Mark’s understanding, not independent proof of a biological relationship.
The 2015 DNA Comparison
In 2015, Mark and Tracey took part in a televised DNA comparison. Tracey was Sammy and May’s biological daughter, making the sibling comparison relevant to Mark’s belief.
The result found that Mark and Tracey did not share a common biological parent. It did not involve an independently obtained DNA sample from Sammy himself. I think that distinction is important: the test answered the sibling question directly, while the broader public narrative often compressed it into a much simpler paternity headline.
Both continued to regard one another as brother and sister after the result. The test did not undo their childhood or their family relationship. It also did not identify Mark’s biological parents, whose names remained unknown to him afterward.

Tracey Jeff and Manny
Tracey Davis was born on July 5, 1961, and died on November 2, 2020, at age 59. Her willingness to take the test made her part of Mark’s search, but I would not reduce their relationship to that one public event.
Jeff was adopted by Sammy and May in 1965. His precise birth chronology is less firmly established here. He survived May and remained part of the family outline alongside Mark.
Manny Davis was adopted by Sammy and his third wife, Altovise Davis. He belongs to Mark’s wider family through Sammy, but he was not May Britt’s son. That distinction prevents the different marriages from collapsing into one household.
Mark’s adoptive paternal grandparents were Sammy Davis Sr. and dancer Elvera Sanchez. May’s parents were Hugo and Hillevi Wilkens. I would not add more remote names without firmer confirmation.
Work and Later Family News
Mark did not build a public performing career comparable to his father’s. Secondary accounts describe assistant stage management work for Sammy during the 1980s, but a complete employment chronology is not established.
In 2015, he was described as working at a Costco photo counter. Descriptions of financial hardship from that period are not a present asset statement. No reliable current salary, net worth, or business valuation is established.
May Britt died on December 11, 2025, at age 91 in Los Angeles. Mark confirmed her death publicly. That later appearance returned him to attention as her son, rather than through a new career announcement.
