The Northampton 1950 directory has a Dora A. O'Connell living on 181 Chestnut St. widow of Frank up to 1958. In 1959 she is not listed but there is a Dora O'Connell listed in Holyoke at 1425 nothampton St.in 1959. Sometimes the directory's will give a death date or say the person has moved but I did not find anything like that.
