Early Life

Mark was born on April 6, 1960. Sammy Davis Jr. and his wife May Britt took him in as a toddler in 1963. He is the oldest of the singer’s four kids. His parents had married in 1960, a time when many Americans were angry about mixed-race marriages.

Career

Mark stayed away from show business and worked at a Costco photo counter. In 2015, he shared his life story in an interview with the Daily Mail.

His Father

The entertainer was a huge star. He sang, acted, danced, and did comedy, and he was part of the Rat Pack with Frank Sinatra and Dean Martin. Two of his best-known songs are “I’ve Gotta Be Me” and “Mr. Bojangles.” He died of throat cancer on May 16, 1990, at age 64.

Mark says that near the end, his dad pulled him close and told him, “You are my son.”

Tracey Davis was born in 1961 and became an author who wrote books about her father. She died on November 2, 2020, at age 59 and his brother Jeff joined the family in 1965.
