Former teacher and archaeologist Frederica Rockefeller Dimmick, 84, of Bourne died November 17. She was a recent resident of Atria Woodbriar in Falmouth.

She was the wife of David Dimmick for nearly 60 years.

Known as Freddie, she was the daughter of Warren Willis Rockefeller and Frederica Elizabeth (Coon) Rockefeller.

Ms. Dimmick grew up in Red Hook, New York, where she was valedictorian at Red Hook High School. As an undergraduate, she attended Syracuse University and Mount Holyoke College. She studied French at Middlebury College, and obtained her master’s degree in education from Radcliffe.

She wove multiple careers and passions into her life. She taught high school English and French in Red Hook, in Sierra Vista, Arizona, and in Natick. Even while raising three boys, she continued to be an educator as an ESL tutor.

She then followed a lifelong interest in archaeology and earned a second master’s degree from Harvard University in 1987 and began another career. She worked for several cultural resources firms and then spent more than two decades with the National Park Service. She retired in 2015 as the archaeologist for the Cape Cod National Seashore.

Ms. Dimmick served as president and trustee of the Massachusetts Archaeological Society (MAS), and her research was published in such journals as the Journal of Archaeological Science and North American Archaeologist.

After her retirement from the National Park Service, she continued to be active with MAS and the Bourne Society for Historic Preservation, including stints in costume as a docent for the Briggs-McDermott House in Bourne.

She was active in the Unitarian Universalist Fellowship of Falmouth over the last 10 years. Previously, she was active with the Eliot Church of Natick for 40-plus years. She loved to sing and was part of the choir in both congregations. She also loved nature, music, taking walks, gardening and watching PBS programs over the years with her favorite being “Masterpiece Theater.”

In addition to her husband, she leaves three sons, Tod Dimmick and his wife, Jennifer Dimmick, Warren Dimmick and his wife, Christine Dimmick, and Andrew Dimmick and his wife, Joanna Dimmick; four grandchildren; her brother, Phil Rockefeller; two cousins; and many other relatives.

A memorial service will be Friday, November 29, at 11 AM at the Unitarian Universalist Fellowship of Falmouth, 840 Sandwich Road in East Falmouth.

Burial will be private.
