From Wikipedia’s history of Colerain Township.
The community was named after Coleraine, Northern Ireland, the ancestral home of a share of the first settlers. A post office called Colerain was established in 1825, and remained in operation until 1907. Colerain was originally built up chiefly by Quakers from North Carolina and Virginia, who left those states due to their opposition to slavery.
