The log mill was built by Hans Brubaker as a grist and saw mill sometime between 1717 and 1729. The mill and a 150 acre farm were sold to John Stoneman in 1729. The property and mill was owned by John [Johannes]Stonen or John Stoner or Johannes Steiner- possibly all various spelling for John Stoneman, Christian's son. The datestone indicates the new mill was built in 1767 by Johannes & Barbara Steiner, the owners of Abbeyville Mansion nearby on Columbia Ave.

J.S. Graybill owned the mill in 1826, J.S. Kauffman milled in 1860, associated with D. Miller's Jefferson Tavern in 1864, operated by Samuel Binkley in 1875, and operated as West End Park in the 1890's by Aaron H. Summy. It is probably at this time that the mill took on the name of Maple Grove, as Summy planted many maple trees near the mill.

At the time of the fire at 2:30 AM Thanksgiving morning, Nov. 24, 2005, the mill was owned by Ecklin Development Corp, having bought the mill from the county in 2001 for $1.00. Robert Ecklin had plans of renovating the mill to lease as offices and retail shops.

The blaze was fought by about 50 firefighters from a dozen companies, mainly with a defensive thrust-to keep nearby structures from burning too. The intersection of Columbia Ave. and Stone Mill Road was closed for close to six hours during the blaze that was fought strongly for 3 hours, then 3 hours of securing and mop up procedures.

No cause was apparent until investigations the next day; then, carelessness with fire by a homeless man using the mill as a shelter was suspected. *Thanks to Robert Kinsey, Thomas Kipphorn, and Wanda Smale for prompt notification of the unfortunate occurrance*

Ralph W. Coho, in 1912, bought the concern and converted it into an amusement park- including a 1.5 million gallon swimming pool. The mill building being used for pool chemicals/supplies storage. The Cohos sold the amusement park in the 1950's and the pool, mill, and land in 1978 to Christ & Elaine Hampilos. The pool, a 7 acre complex, was sold in 1986 to Lanecor Associates, who developed the Stone Mill Plaza Shopping Center across Stone Mill Road from the mill. The pool was operated into 1988 to comply with a purchase zoning variance concerning the Plaza Center.

The fire damage-repaired Maple Grove Mill, December, 2013, south side. In 1993, the pool, mill, and surrounding land, were signed over to Lancaster County by a holding company, Ohio-Pennsylvania Properties II, for settlement of unpaid real estate taxes incurred by Lanecor earlier.
