In 1801 Cool
Spring was the name chosen to designate the southeast quarter of Mercer
county. In 1802 this name was applied to what is now the east central
portion of the county. In 1805 the township was restricted to about the
area now comprised in Cool Spring, Jackson, Fairview and Lake townships.
In 1850 this area was divided into the four townships as they now stand,
Cool Spring being the southwest quarter of the former township of that
name.
Benjamin
Stokely, was the first settler in Cool Spring, in 1796. Other
pioneers were Joseph and William Alexander, Aaron
Hackney, Robert and Joseph McDonald, the Johnston
family, Hugh McKean, William McMillan, the McEwens,
and that notable pioneer preacher, Samuel Tait.
Many of the associations dearest to the people revolve about the early
Presbyterian churches of this township.
As Cool Spring
township adjoins the borough of Mercer, the residents of the township
from the early years have made this borough their principal trading
point. William North, an Englishman, who
settled in the northeast corner of the township about 1822, gave the
name to the community which has been known as North’s Mills. A
postoffice was established there in May, 1858, and discontinued several
years ago when rural delivery became general. Otter Creek became a
postoffice in 1872, but has also been discontinued. Cool Spring station,
a flag station on the railroad, marks this settlement.
Cool Spring
township has come into prominence in recent years because of its oil
wells. Otherwise it has for more than a century been rural community
made up largely of Presbyterian farmers.
