There is one Daniel Sullivan who is listed on the Social Security death index who was born in the spring of 1878: 4 March 1878. He passed away in January 1971 and his last residence was East Walpole, Norfolk County, Massachusetts.
Most deaths on the index occurred after the mid-1950's (someone else can more clearly state the facts, since I don't have them). If Daniel passed away prior to the 1950's, he would not be listed.
I have to leave for a few hours, but I will check back here later.
