Early life and adoption
Mark is widely reported as being born in 1960. He later became the adopted son of Sammy Davis Jr. and actress May Britt. Reliable biographies say Sammy and May had one biological child, Tracey Davis, and they adopted two sons: Mark and Jeff.
May Britt’s own biography gives more detail: it lists Mark’s adoption as June 4, 1963, and names him “Mark Sidney Davis.” This page also notes the couple adopted Jeff in 1965. While some sources spell the middle name “Sydney,” others use “Sidney.” Because May Britt’s bio is carefully sourced and lists adoption dates, it is a helpful reference for the adoption timeline.
The family around him
To understand Mark’s life, it helps to know the wider family. Sammy Davis Jr. was a very busy entertainer, singer, dancer, and actor, who worked almost all the time. News reports and biographies agree that his schedule made family life hard. He and May Britt married in 1960 and divorced in 1968. They had Tracey (born 1961) and later adopted Mark and Jeff. After the divorce, Sammy married Altovise Gore; together they adopted a son, Manny.
Tracey grew up to write about her life with her father in the book Sammy Davis, Jr.: My Father. A trusted chronology of the book notes again that Mark was adopted in 1963, reinforcing the record about his early years.
Tracey later died in 2020 at age 59, which was reported by major outlets. This shows how public the family remained, even decades after Sammy’s death.
Was Mark Sammy’s biological son?

For many years, there were rumors about whether Mark was the biological son of Sammy Davis Jr. Mark himself wondered about this and, as reported in 2015, he took a DNA test. The show said the test did not show a biological match with Sammy. This does not change Mark’s legal and family ties, but it helped answer a question that followed him for years.
Some later summaries and profiles repeat those DNA results and say that Mark is not the biological child, while also noting that Sammy told Mark on his deathbed, “You are my son.” This shows the difference between biology and family love in Mark’s story.
Life out of the spotlight
Compared with his famous father, Mark keeps a low profile. Reliable, mainstream sources do not offer many details about his private job or daily life. One widely viewed TV segment mentioned that he worked as a photo clerk, which fits the idea that he chose a simple, private life. Because we want to rely on confirmed information, we do not add claims that are only from gossip blogs.
What we can say with confidence is that Mark grew up in a complex, public family. Sammy was a star who faced racism and busy work schedules. This affected his time with his children, something noted in historic coverage and in family accounts. Even so, Mark remained part of the Davis family picture and history.
Names and spelling: “Sydney” or “Sidney”?
You will see both spellings, Sydney and Sidney, for Mark’s middle name. May Britt’s biography page uses “Sidney,” while other outlets and public records use “Sydney.” Because the May Britt page lists an adoption date, it is a strong source for the spelling “Sidney,” but both versions appear in public records and reporting. When writing about him, it is fine to note both forms.
Mark’s place in Sammy Davis Jr.’s legacy
Mark is part of a famous and sometimes difficult legacy. Sammy Davis Jr. broke barriers in show business and in American life. He also had personal struggles and made choices that affected his family. Reliable obituaries and profiles note that he missed time with his children due to his career. Still, the children, including Mark, are part of how people remember Sammy today: not only as a star, but also as a father who had a complex family life.
Why this story matters

Mark’s story shows that family is not only biology. Adoption builds real families. Sammy’s reported words to Mark, “You are my son,” express this bond. Even when DNA results said otherwise, the relationship between them still mattered. Mark’s quiet life tells us that not every child of a star wants fame. Some choose privacy and normal work, even when the world knows their last name.
Conclusion
Mark Sydney Davis’s story is a touching example of how love and care can build a true family. Even though questions about his birth and adoption have followed him for years, his place as Sammy Davis Jr.’s son is real and meaningful. His life shows that being part of a family is not only about sharing DNA, but about the bonds people form through love, trust, and respect.
