Eileen Sullivan Mayhew died on May 21 after celebrating her 101st birthday with her family and friends at Long Hill in Edgartown.

Born in Melrose on May 11, 1915, Eileen was the seventh of the 10 children of Margaret (Sidley) and John Sullivan of County Cork, Ireland. She attended St. Mary’s Parochial School in Melrose and then Cheverus High School in Malden. She graduated from Emmanuel College in Boston, class of 1937, having majored in biology and chemistry. After graduating, she studied at Massachusetts Memorial Hospital to become an X-ray technician.

Eileen came to Martha’s Vineyard in 1938 to work as the first X-ray and laboratory technician at the Martha’s Vineyard Hospital. She married Benjamin C. Mayhew Jr. on Jan. 18, 1941. A fisherman’s wife, Eileen was instrumental in getting the town of Chilmark to approve women scalloping in Menemsha and Quitsa Ponds.

She served briefly as the Chilmark Postmistress and was involved with the Chilmark Community Center and the Town Affairs Council. Eileen was a strong supporter of her husband’s political involvement in the community as selectman of Chilmark and as the representative of Dukes County in the Massachusetts State House. She was a loving, dedicated mother to their five children.

Eileen was predeceased by her husband in September 1969 and her daughter Eileen Mayhew May in January 1999. She is survived by her three sons: Benjamin (Skip) Mayhew 3rd 3rd and his wife Cristina of Edgartown; Gregory Mayhew and his wife Lois of West Tisbury; and Jonathan Mayhew and his wife Anne of Chilmark; and one daughter, Margaret PĂ©nicaud and her husband Dominique of Chilmark. She had 27 grandchildren and 33 great-grandchildren.

A funeral Mass will be celebrated at 10 a.m. on Saturday, Sept. 10 at St. Augustine’s Church in Vineyard Haven, followed by a celebration of her life at the Chilmark Community Center at about 11:30 a.m.
