JACKSONVILLE, Fla. (AP) _ Eight family members, including a 62-year-old matriarch and her 16-year-old grandson, were arrested and charged Wednesday with running a thriving, drive- up crack cocaine service.

''We sat out there for an hour and a half and we counted 47 different transactions. That's busier than any 7-Eleven in town,'' said detective Rick Graham of the Jacksonville Sheriff's Office narcotics unit.

The eight were arrested in a raid of their home early Wednesday morning. Three other people also were charged.

Police said the family and their friends ran a crack service that made more than $100,000 a year selling drugs to dozens of people an hour.

Among those arrested Wednesday was the head of the family, Gussie Mae Nelson, 62, who police said was selling crack along with at least six of her 11 children. She was charged with trafficking in cocaine, sale of cocaine and cultivation of marijuana, which was growing in the back yard of the house.

Also arrested were three of Ms. Nelson's sons, twins Ronnie and Donnie Hadden, 30, and Mike Nelson, 41. All were charged with sale of cocaine, and Ronnie Hadden additionally was charged with trafficking.

Two of Ms. Nelson's daughters, Sharon Hadden, 22, and Gloria Hadden, 37, were charged with selling cocaine, as was her 16-year-old grandson, Canaryshin Hadden, and a nephew, Richard Williams, 34.

Police said they had received dozens of complaints from neighbors, some of whom supplied detailed information about people and cars that frequented the area.
