If you know the date of her death, you could write for a copy of the death certificate to the town clerk in the town of death. (Usually a fee of $5.00). The name of the funeral home will be listed on the death certificate. Then, you may contact them for further info. (There may not have been an obituary, possibly just a listing.) The cemetery would be on the death certficate as well. Also, the Mass. Registry in Dorchester would have info.
