The community was named after Coleraine, Northern Ireland, the ancestral home of a share of the first settlers.[4] A post office called Colerain was established in 1825, and remained in operation until 1907.[5] Colerain was originally built up chiefly by Quakers from North Carolina and Virginia, who left those states due to their opposition to slavery.[6]
