The first grandchild of slain civil rights leader Martin Luther King Jr. is a girl.

A family spokeswoman says Arndrea Waters King, wife of Martin Luther King III, gave birth to Yolanda Renee King on Sunday at Northside Hospital in Atlanta. Spokeswoman Sandra Tarver says the mother and baby are healthy.

The baby was named after her aunt, Martin Luther King Jr.'s eldest daughter Yolanda, who died in May 2007, Tarver says.

Martin Luther King III married shortly after his mother's death in January 2006, but the wedding was not made public until this year.

He was the first of Martin Luther King Jr.'s four children to marry and the first to have a child.
