Veronica LeTourneau Colfer, 100, who did volunteer work in the 1980s and ’90s with organizations supporting gay rights, died Nov. 20 at the Sacred Heart Home, a nursing home in Hyattsville.

She had pneumonia, said her son, Paul Colfer.

Mrs. Colfer’s son said that she began her volunteer work after he told his parents that he was gay. She worked with Parents, Families, and Friends of Lesbians and Gays, the organization also known as PFLAG, and with DignityUSA, a group of gay and lesbian Catholics.

Veronica Esther LeTourneau was born in Hibbing, Minn. She settled in the Washington area in 1933 and did secretarial work for the federal government for more than 15 years.

In the 1950s and ’60s, she did charity fundraising and volunteer work with pediatric cancer patients. She was a den mother for her son’s Cub Scout troop.

Mrs. Colfer was a longtime Silver Spring resident. Her husband of 66 years, Gerald F. Colfer, died in 2002. Survivors include two children, Paul Colfer of San Francisco and Geraldine Ennis of Pinehurst, N.C.
