Katrina A. Kelley, 52, a former aide to two Illinois congressmen who later did advocacy work for the National School Boards Association in Alexandria, died Oct. 9 at Howard University Hospital.

She had kidney failure, said her sister Karen Kelley-Ariwoola.

Ms. Kelley worked for former Rep. Lane Evans (D-Ill.) in the 1980s, becoming a legislative assistant for domestic issues. From 1988 to 1992, she worked as a legislative assistant and legislative director for former Rep. Charles A. Hayes (D-Ill.).

In 1992, she joined the National School Boards Association, a nonprofit organization that represents state school board associations and their members. She stepped down in March as director of the organization’s Council of Urban Boards of Education, her sister said.

Katrina Ann Kelley was born in Galesburg, Ill. She was a 1984 social work graduate of the now-defunct Marycrest College in Davenport, Iowa. She was a Washington resident.

Survivors include her mother, Joan Milam Kelley of Arlington; three sisters, Manda M. Kelley and Karla R. Kelley, both of Washington, and Karen Kelley-Ariwoola of Minneapolis; a brother, William E. Kelley Jr. of St. Louis; and a half-brother, Robert L. Smartt of Plainsboro, N.J.
