Jane Sanger died peacefully on Wednesday, Jan. 26, at her home in Duxbury.

She was 86. Her beloved John P. Eustis 2nd was at her side. Her husband of 50 years, W.R. (Bert) Sanger, died in 1999.

She was born Mary Enid Jane Craig on Dec. 17, 1924, in Philadelphia, Pa., to Mary Enid Pritchard and Charles Winchester Craig. Raised in the Philadelphia area, she graduated from Pembroke College at Brown University in 1948. After Jane and Bert were married in that year, they made their home in a number of communities, including Shaker Heights, Ohio, Ho-Ho-Kus, N.J., Weston, where they lived for over 30 years, and Edgartown.

In 2005 Jane moved to the village of Duxbury, where she shared a life with Jack Eustis for the past 29 months. Blessed with pluck and a knack for sprees of every kind, Jane often found good use for her brilliant personality. A lifelong volunteer, Jane will be remembered by many for her company and service at the Valley Hospital in Ridgewood, N.J., at the Boston Symphony Orchestra, at WGBH, the Winsor School, Noble and Greenough School, and at the Martha’s Vineyard Preservation Trust, as well as at other Vineyard organizations. In attendance at Boston Symphony Hall on Friday afternoons for decades, Jane cochaired the annual Musical Marathon in 1983. Ever awed by nature, she was also an avid gardener, weather enthusiast and bird-watcher. Yet her first and last love were her many friends and family. Jane will be missed by all who knew her warmth, enduring curiosity and beautiful smile.

She is survived by her husband, Jack Eustis of Duxbury; her brother, Cassin Winchester Craig and his wife Jeanne, of Gwynedd, Pa.; her daughter, Noel Gearhart and husband Peter; and her son, Craig Sanger, all of Wellesley; her grandchildren, Abigail Giles, Matthew Giles, Kathryn Sanger and William Sanger. She also leaves behind two step-granddaughters, Alice Gearhart and Julia Gearhart, as well as several nieces and nephews. In addition to her first husband, Mrs. Sanger was predeceased by her brother, Donald Winchester Craig.

A funeral service will be held at St. Andrew’s Episcopal Church in Edgartown, on Monday, Feb. 7, at 11:30 a.m. Interment at Tower Hill Cemetery in Edgartown will be private.

In lieu of flowers, the family requests memorial donations to St. Andrew’s Episcopal Church, 34 North Summer street, Edgartown, MA 02539.
