Charlotte S. Geary, 83, a former doctor of chiropractic medicine and a member of the Takoma Park Seventh Day Adventist Church for most of her life, died of cardio-respiratory failure Friday at Suburban Hospital in Silver Spring.

Mrs. Geary was born in Allegheny County, Pa. Her family moved to Takoma Park when she was a child and she joined the Takoma Park Seventh Day Aventist Church at that time.

When she was a young woman, the future Mrs. Geary and her father, Neville Staughton, studied chiropractic medicine together and became doctors of that discipline. The young Dr. Staughton practiced in Takoma Park until her marriage in 1929 to John J. Geary.

The couple moved to Silver Spring at that time and Mrs. Geary lived there for the rest of her life. Mr. Geary was the resident manager of the Falkland Apartments in Silver Spring until his retirement in 1956. He died in 1957.

In addition to her work with the church, Mrs. Geary was a member of the Martha Washington Chapter of the Daughters of the American Revolution and for many years was chapter historian.

Survivors include two daughters, Patricia G. Kennedy of Silver Spring, and Charlotte G. Francis of Little Rock, Ark.; three sisters, Eloise Vannix of Camarillo, Calif., Laura Leizer of Waldorf, Md., and Elizabeth Dowell of Tallahassee, Fla., and seven grandchildren.
