Sharon Rayner Nangle, 63, of Havertown, a faculty assistant at Haverford College for 24 years and a community activist, died Friday at Bryn Mawr Hospital of myelodysplasia, a bone-marrow disease.

Mrs. Nangle loved the Haverford faculty, said her husband, Samuel Nangle Jr., and continued to work part time until November while battling her illness.

Fourteen years ago she was diagnosed with leukemia, he said, and underwent a bone-marrow transplant. She became ill again 21/2 years ago.

A graduate of Haverford High School, Mrs. Nangle earned a bachelor's degree from Rosemont College in 1966. For a year she worked for the National Security Agency in Maryland, and then for three years, she was assistant to Ruth Selzer, the society writer at The Inquirer, until the birth of her first child.

Mrs. Nangle was past vice president and a 12-year member of the Haverford Township school board. She was past president of the board of Llanerch Presbyterian Church. She doted on her two grandchildren, her husband said.

In addition to her husband of 41 years and grandchildren, Mrs. Nangle is survived by sons John and Paul; a daughter, Dana; parents, James and Charlotte Rayner; and a sister.

The funeral will be at 11 a.m. today at Llanerch Presbyterian Church, Park Road and Lansdowne Avenue, Havertown.
