Frank S. Yeomans of Chilmark died of natural causes on Sept. 2. He was 80.

He was born on Oct. 23, 1939 in New York city, the son of Ann Sears and Moreau Yeomans.

Frank attended Milton Academy, graduated from Harvard College in 1961, and graduated with a master’s degree from Trinity College in Dublin, Ireland. He was a star sprinter while attending Harvard. Early in his career he was a history teacher, but soon after that became a wealth advisor. He worked for several Boston firms prior to starting his own company, First Lexington Capital.

He had three children, Stephen, Peter, and Christopher. Peter died tragically at age four in a drowning accident in Canada.

Frank’s many interests included tennis, rugby, wrestling, track and field, and sailing. He was most relaxed while sailing and owned a 35-foot sailboat for many years. After he moved to Martha’s Vineyard, he became involved in local politics and served on the Chilmark finance committee.

He is survived by his wife Sylvia Yeomans; two sons, Stephen, and Christopher and his wife Jennifer; and his stepson Adam and his wife Aimee.

Services will be private with immediate family. A celebration of life will be held at a later date.
