Dorothy (Orisondo) (Roosen) Diebold, 105, died at Toplands Farm in Roxbury, July 6, 2010.

She was born Feb. 3, 1905, in Brooklyn, N.Y.

Mrs. Diebold attended the Ogontz School in Pennsylvania, where she excelled in field hockey and book binding and studied the works of John Galsworthy, before making her debut in New York City, marrying Albert Richard Diebold there in 1931.

A stalwart of the St. James Church altar guild in New York City, as well as that of Christ Church in Roxbury and St. Andrew's Church in Boca Grande, Mrs. Diebold was an award-winning needle-pointer, who made many pieces for her churches, including the kneelers used to this day.

She was an active member for decades of the Colony Club and Junior League in New York City and the Boca Grande Woman's Club.

An avid gardener, she was involved with the Roxbury-Bridgewater Garden Club for many years.

A scratch golfer, Mrs. Diebold particularly enjoyed playing the game at the Washington Club with her mother, when both were well along in years.

Mrs. Diebold was a member of the Red Cross Ambulance Corps in New York City during World War II, and followed her husband to Washington, D.C., when he served in the U.S. Army there during that conflict.

She was a great supporter of many charitable causes in Florida, Connecticut, and elsewhere, including the Roxbury Land Trust, The Christian Herald Association, Roxbury, and Boca Grande fire, ambulance, library and churches.

She was known as a formidable grande dame and arbiter of social correctness.

Mrs. Diebold taught her grandchildren to call her Mumsie and, somewhere along the line, everyone started calling her Mumsie.

She was preceded in death by her husband, Albert Richard Diebold; her mother, Clarita (Orisondo) Roosen; her father, Herman Dudley Roosen; two sisters, Clarita Roosen, and Helen (Roosen) Curran; two brothers, Berend Roosen and Robert Roosen; and a grandson, Albert Richard Diebold III.

Long a fixture of New York City, Palm Beach, Boca Grande, Florida, and Roxbury, Mrs. Diebold is survived by her children, Albert Richard Diebold, Diane Diebold Terni, and Dudley George Diebold, and his wife, Honoria (Hine) Diebold; her grandchildren, Deborah (Diebold) de Naveja, and her husband, Juan-Maria Naveja de Anda, Linda Gavel Webb, and her husband, Arthur Heberer III, Daphne (Diebold) Stoughton, and her husband, James Stoughton, Frank Gavel Jr., and his wife, Laurie (McKee) Gavel, Stephen Gavel, and Caitlin Diebold, and her husband, Kevin O'Connell; and her great-grandchildren, Juan-Maria Naveja Diebold, Thomas Gavel, Charles Webb, and Rebecca Gavel.

In addition, Mrs. Diebold leaves behind dear friends Shirley Gilbert, and Olive Simpson, as well as nurses and staff in Roxbury and Boca Grande, who gave her kind care for many years.

Mumsie will be eulogized today (Friday) at 11 a.m. at Christ Church in Roxbury. Burial will be private.

The Lillis Funeral Home of New Milford is in charge of arrangements.

In lieu of flowers, a memorial contribution may be made to the Christ Church, 24 Church St., Roxbury, CT 06783 or the Roxbury Volunteer Fire Department, 27 North St., Roxbury CT 06783.
