Hallie Ramsay Conger, 103, a descendant of colonial era families, died Tuesday at Oak Meadow Nursing Home in Alexandria.

Her great-great-grandfather, William Ramsay, was a founder of Alexandria and built the city's first house, Ramsay House, which still stands at the corner of King and Fairfax Streets. He was married to a first cousin of George Washington's mother, Mary Ball.

Mrs. Conger was born in Alexandria and grew up in another Ramsay house on Prince Street.

As a young woman, she taught Sunday School at Christ Episcopal Church in Alexandria and was a student at the Corcoran Gallery of Art, where she graduated as a portrait and landscape painter.

Mrs. Conger recalled how President Theodore Roosevelt spotted one of her paintings, an ear of corn in its husk, at the gallery and took it back to the White House. His intent, she said she learned, was to present it to Congress in an effort to have an ear of corn made the national flower. But a bill bringing that about failed to pass.

In 1900, Mrs. Conger left Alexandria for the Shenandoah Valley to recover from an attack of malaria. She established an art school in Harrisonburg, Va., and in 1906 was married to Dr. Clement E. Conger, a well known physician.

While in Harrisonburg, she was an active member of Emmanuel Episcopal Church and during World War I was a leader in Red Cross activities.

Dr. Conger died in 1932. Mrs. Conger returned to Alexandria in 1944 and had lived there since then.

She is survived by two sons, Clement E. Conger Jr., curator of the White House and State Department diplomatic reception rooms, who lives in Alexandria, and Dennis Ramsay Conger, a retired Chesapeake & Potomac Telephone Co. official, f Manassas; five grandchildren and one great-grandchild.

The family suggests that expressionsof sympathy may be in the form of contributions to the Restoration Fund of Christ Church in Alexandria.
