Sullivan Square was made in 1889. It honors Jeremiah F Sullivan who was the mayor of Holyoke in three different years – 1889 1890 and 1892. FINDAGRAVE Sullivan lived at 1159 Dwight Street for decades (before renumbering on that street the address was 275 Dwight Street). He was on the board of directors of the Holyoke Street Railway and thus one of the trolley lines was right out his front porch. He ran a meat market at 140 High Street.
There was a renovation of the square in 1952 that made all look much better. Trees were removed in that year.
