Judging from their biographies and depictions of their family backgrounds, they don't seem to be related despite sharing a last name.
Lamman Rucker was born October 6, 1971, in Pittsburgh, Pennsylvania. His mother had a dance company (the Pittsburgh Black Theater Dance Ensemble) and his father was a drummer, so entertaining is in his blood.
He was raised in areas around Washington, DC and Maryland area.
Singer-songwriter Darius Rucker on the other hand was born on May 13, 1966, in Charleston, South Carolina. Rucker later described his childhood as a "typical Southern African-American upbringing," involving long hours at church on Sundays and enduring various financial struggles.
At many points in his life, his mother, two aunts, maternal grandmother and 14 children lived together in a three-bedroom apartment.
