Petre remembers Miller as "a lovely child. She always helped me check the work of the younger children."
"She was a dear,'' Petre said, "the oldest girl who deserves a lot of credit for helping out her family at home."
Miller was the first of eight children born to Percy and Betty Myers, who owned a farm on the Downsville Pike.
She had to help raise the children when their mother died suddenly, said Milton Myers, 76, one of Miller's younger brothers.
The youngest child, now 66, "was still in a high chair when my mother died," Myers said.
He said he has always been close to Miller. "We used to pull pranks on each other when we were children," he said.
Petre recalled the Center Hill School as one of three one-room schools where she taught in Washington County.
She was graduated from the old Broadway High School and earned her teaching certificate during six weeks of summer school in Towson, Md., she said.
She had to quit teaching after eight years because she got married. "They wouldn't let married women teach in those days," she said.
Petre returned to the classroom as a substitute teacher after her family was grown. She retired in 1962.
Being a housewife and mother was Miller's lifework. She and her husband had been married more than 59 years when Millard Miller died in November of 1995.
The couple had seven children, including a set of twins. Miller worked little outside her home, her brother said.
She was having a great time Saturday. The party was not a surprise. It was more a celebration of her life. She stood in front of the door of the church hall as a reception line of one, greeting each guest as they came in.
"This is just a great day, I just love it," she said.
