Mary also donated for a playground in Woburn, later renamed Gonsalves Park. Mary entrusted the park to the City of Boston, according to friends who were quoted in the newspaper after her death, because she believed that a Greater Boston would formally incorporate its suburbs just as New York City had incorporated the surrounding towns as boroughs and other American cities had followed a similar model. Boston had already incorporated several formerly adjacent towns such as Roxbury, Dorchester, Brighton and Hyde Park. Although she specified the City of Boston as the trustee, the "public" are the beneficiaries. She had a vision for her park that it was to be enjoyed by all.
