 When the town wished to established a post office, they discovered that the post office name Millersburg, Indiana had been taken.After some frustration and consideration, on September 18, 1849 they choose the name Collamer, after President Zachary Taylor's Postmaster General Jacob Collamer.Built along the north side of the Eel River, the community by 1880 had a "gristmill, a sawmill, two general stores, a drug store, a boot and shoe store, a grade school, a Christian Church, a physician and a post office."
