KITTERY, Maine - Mara Frost Marshall, 94, transitioned peacefully in her home on March 10, 2015, surrounded by her loved ones. Born at the historic Frost Garrison in Eliot, Maine on January 18, 1921, she was a daughter of Henry Martin Frost and Annie (Eldridge) Frost. She attended a local one-room schoolhouse, graduating from Eliot High School in 1940, and from the University of Maine in 1976. With her husband, the late Willard C. Marshall, she made a home and raised a family on Lemont Lane in Kittery. Mara was a beloved third-grade school teacher at the Horace Mitchell School in Kittery Point, retiring after many years at the age of 71. She dearly loved her students and the numerous teachers with whom she worked. Following retirement, she continued mentoring young people with the Grandparents Group in Kittery. Mara greatly enjoyed singing and sang for many decades in the choir of the Second Christian Congregational UCC in Kittery where she was a member, and also sang in the Seacoast Community Chorus. More recently she attended the First Parish Congregational Church in Dover, NH with her family. As a 12th-generation New Englander, Mara was deeply rooted in local history and collected books by local authors, records and also dolls. She enjoyed numerous years as a docent at the Kittery Naval & Historical Museum. In later life, she became an avid seeker of spiritual growth through the many volumes she collected, read and shared with anyone interested. Highly recognizable, even in advancing years - and always dressed in blue - Mara was frequently approached by many of her students in public for a quick update, or seen chatting with her beloved neighbors on her daily walks. Mara is survived by three generations of loving family: daughter Bonnie Marshall and husband Alan Bean of Wells, son Geoffrey and wife Norma and son John and wife Lisa, all of Eliot; six grandchildren: Sean Marshall and wife Angie of S. Berwick, Allison and husband Kurt Geller of York, Christopher Marshall and wife Katie of Dover, NH, Alex Marshall and fiance Elizabeth Hoyt of S. Portland, and Angela and Katy Marshall, both of Seattle, WA; five great-grandchildren: Brooke, Grady, and Maggie Geller, and Bodhi and Eva Marshall; three stepsons: Alden, Barry and Bruce Marshall; and five nephews and nieces. She was predeceased by her two much beloved brothers, genealogist John E. Frost and historian Joseph P. Frost and a sister, Mary Waterhouse of Rumford, ME. Friends may visit her family on Friday April 10, 2015 from 6-8 PM in the J.S. Pelkey Funeral Home, 125 Old Post Road, Kittery Maine 03904. A memorial service will be celebrated on Sunday April 12, 2015 at 1 p.m. in the First Parish Congregational Church at 218 Central Ave., Dover, NH. In lieu of flowers, donations may be made to the Kittery Historical & Naval Museum, POB 453 Kittery Maine 03904. Arrangements are entrusted to the JS Pelkey Funeral Home of Kittery.
