The McVille post office was established on May 5, 1864, with Robert McCaslin as postmaster.[2][3] It remained in operation until 1903.[2] That same year, 1864, John Boyd opened a store about 190 yards northwest of the steam mill then located on the west side of Nicholson's run.[3] The first and only resident clergyman at McVille in 1883 was Rev. Jacob F. Dean, Baptist, who settled there in 1868.[3]
McVill P.O. appears in the 1876 Atlas of Armstrong County, Pennsylvania.[4]
