hallock_twp.html: "About 1825, settlers from the
East began to drop into the district, Simon and
Aaron Reed came from Jackson county, O., in
November of that year. The only village situated entirely within the township [Hallock] is that of Northampton, on Sec. 13, which was laid off by Reuben Hamlin and Mr. Freeman in July, 1886. The first house therein was also the first erected in the township as a tavern. It was built in the Winter of 1835-6 by Reuben Hamlin, and was kept as a public house by him for many years. He came from near Northampton, Mass., and he named the village, of which he was the founder, after it. Aaron Reed was the first settler near the site of the village, and his old log cabin was replaced by the house which stands beside the bridge, near the south end of the village."
