Editing Shade Township, Pennsylvania (section)

===Cairnbrook===

In the central part of Shade Township is a mining town laid out in 1912 by the Lolayhanna Coal and Coke Company on the Jacob McGregor Farm. It is located on the west bank of Dark Shade Creek along State Route 160. It is the largest unincorporated town in Shade Township, with a present population of 750. The Cairnbrook post office was established here in 1914. The first postmaster was Charles Severn and the present one is Jennings Reitz (as of 1964). The Shade-Central City Union, Junior-Senior High, and elementary schools are located here. The Graef Lutheran Church and parsonage were erected here in 1917–18 at the corner of McGregor Avenue and Third Street. Dorfman and Hoffman established a clothing factory here in 1955, which employs approximately 185 workers at the present time.

Cairnbrook, although not incorporated, owns and operates its own water company, sewers and disposal plant, and street lighting, under the management of the Cairnbrook Improvement Company, Inc. Each property owner is a stockholder in the company. All streets are hard-surfaced and lighted.

The [[Cairnbrook Historic District]] was added to the [[National Register of Historic Places]] in 1994.<ref name="nris">{{NRISref|version=2010a}}</ref>
