Mildred "Billie" Elizabeth (Knight) Worthington, 100, a resident of Watermark at East Hill in Southbury, died Sept. 28, 2012, at Danbury Hospital. She had fallen on Sept. 18. Mrs. Worthington was the widow of Elmer Harry Worthington.

Mrs. Worthington was born July 28, 1912, in Winter Haven, Fla., to Ignatius and Viola Knight.

At 16, she graduated from Winter Haven High School in 1929 and entered Orange General Nursing School in Orlando, where she earned a registered nurse degree at age 18.

Too young to get her Florida license, she went to the advanced nursing program at Women's Hospital in Baltimore, where she took post-graduate training in obstetrics and then went to Philadelphia Hospital to focus on mental and nervous disorders.

When she first entered nursing school, the new students were asked to write on a card what they wanted to be called. She didn't like Mildred and her best friend in high school was "Billie," so she wrote on her card, Billie Knight, and that became her name.

Her half-sister, Mae, was married and living in New Milford, so Mrs. Worthington went to New Milford, received a nursing license in Connecticut in 1933 and was employed at New Milford Hospital.

She met a young bank teller, Elmer Worthington, a New Milford native. They married in 1934. She worked until she became pregnant in the mid-1930s.

After World War II, the Worthingtons (with a son and two daughters) moved to Bridgewater, when Mr. Worthington began commuting to New York City as an officer of Banker's Trust. In 1946, they moved to Roxbury, where they lived, raising their family, until moving to Watermark (then East Hill Woods) in 1998.

Mr. Worthington worked in New York City until retiring in 1976. He was later an officer at Danbury Savings Bank until 1980. He died at age 91 in 2002. He is buried in the family plot in Stafford.

Both Mr. and Mrs. Worthington were known for their volunteer work in Roxbury. They worked for the local Democratic Party, the Roxbury Congregational Church, the Roxbury library, the Booth Free School and the town of Roxbury.

Mrs. Worthington served on numerous volunteer boards.

During their retirement, the couple traveled frequently, continued to do volunteer work and enjoyed life.

Mrs. Worthington was active in sports competition at Watermark, played bridge and poker weekly, and worked for several volunteer programs at Watermark.

The highlight of her later years was celebrating her 100th birthday in July. More than 200 relatives and friends from around the world joined in the festivities. Her children and grandchildren created a 120-page book of her life.

She was known as an impressive woman who had served as a mentor to numerous younger women.

Mrs. Worthington is survived by a son, Bob Worthington, and his wife, Anita, of New Milford; two daughters, June Mendell, of Massachusetts, and Diane Worthington and her husband, Jerry West, of Maine; six grandchildren; and seven great-grandchildren.

She preferred to celebrate life and saw her 100th birthday parties as an alternative to any service for her after death. Therefore, per her request, there will be no services.
