She was the daughter of Scottish Consul David Ross Gillespie and Carmen Edwards Ossandón.
Being the richest man in Chile, Edwards Ossandón was the only one of the Chilean millionaires of the time who did not build a palace in Santiago, nor acquire a great hacienda, or take a pleasure trip to Europe.
[4] Ross Edwards was a benefactor of countless charities, including the founding of hospitals, nursing homes, orphanages, schools and churches, dedicating her entire life to this work.
[2][7] In La Serena, her hometown, she contributed funds for the construction of the cloister and chapel of Divina Providencia, and she also donated the organ that is still preserved in the cathedral.
She bequeathed the sum of ten million pesos to the Roman Catholic Archdiocese of Santiago de Chile for the construction and repair of churches.
