Driver error caused the head-on collision Wednesday that killed a senior Clermont couple and their 57-year-old daughter in North Hall and seriously injured a child, officers said.

Nita Pool True drove a red minivan off the west shoulder of Clarks Bridge Road in the rain, overcorrected and crossed the center lane, which led to the 3:15 p.m. collision, the Georgia State Patrol said.

True was driving south toward Gainesville with her parents, Bernita M. Pool, 90, and Samuel C. Pool, 88. All three family members died at the scene, Hall County Coroner Marion Merck said.

A Gainesville mother and her twin daughters also were injured in the two-vehicle crash when True's van struck their black SUV as it headed north on Clarks Bridge Road.

Angela Jakel, 45, and her 11-year-old daughters, Ava and Chelsea Jakel, were taken from the scene to Northeast Georgia Medical Center.

Ava Jakel later was transported to Children's Healthcare of Atlanta at Egleston. She was listed in stable condition Thursday with fractured ribs and a lacerated liver, a family member said. Angela Jakel and daughter Chelsea were recovering from their injuries at home.

The Pools had lived in Clermont for the last 10 years. Married for 64 years, the couple moved to Georgia after a joyous life spent all over the South and East Coast, their daughter, Nancy Bell, said.

Both Pools served in the Navy during World War II yet met after the war in Dallas, where Samuel Pool worked as an airplane mechanics instructor. She was his secretary.

"They moved around a lot. They had so much fun together," said Bell, who lives in Cumming. "They were a very special couple, had a lot of fun in life and were very, very, very much in love."

Their daughter, Nita, lived and cared for the couple.

The Pools moved to Clermont to be nearer to their children, who include a son, Samuel Pool of Clermont.

"(Nita) lived with them and took care of them," Bell said. "She was the reason they were still able to be in their home."

Funeral services are 2 p.m. Saturday at Strickland Funeral Home Chapel in Clermont. Burial will be in Concord Baptist Church Cemetery.
