The headstones in Pentucket Cemetery tell a grim story of the epidemic that ravaged Haverhill for two years beginning in the fall of 1735. Set in a single row were markers for the 4 children of James and Margaret McHard, each of whom succumbed to the disease in July 1736. The following year, James and Jemima Holgate buried 4 children in a single month. Ebenezer Buck commissioned one gravestone to memorialize the deaths of his 2 adolescent children.
