Marcia's mother was a gifted artist who wrote and illustrated many books—including her last about the island of Aruba.
Eleanor Moore also opened the guesthouse, dubbed the "Barnacle," to painters and sculptors to use as an art studio and give classes—at the Moore family's summer home, the Cuttyhunk Club, in Massachusetts overlooking Vineyard Sound. Friends and family who came to visit would enjoy such activities as motorboat riding, a good swim, or picnicking. Their clever doormat wrote “Moore Fun.”
Doing things like buying clothes for needy children, and sponsoring foreign students through culinary school in the U.S., gained Eleanor Moore such a reputation for helping others, that people took to calling her “Mother Moore.”
Some of the clubs Marcia's mother belonged to included:
Concord Women's Club
League of Women Voters
Ladies Tuesday Club
Emerson Hospital Auxillary
The Concord Antiquarian Society
In addition Marcia's mother was instrumental in:
