John Roll
The community received its name from John Roll McLean, the former publisher and owner of "The Washington Post". Along with Stephen Benton Elkins and French aristocrat Jean-Pierre Guenard, in 1902 he bought the charter for the Great Falls and Old Dominion Railroad. Completed in 1906, it connected the area with Washington, D.C. McLean named a railroad station costing $1,500, of which $500 was raised locally, after himself where the rail line (traveling on the present route of Old Dominion Drive) crossed the old Chain Bridge Road. The community itself was founded in 1910, when the communities of Lewinsville and Langley merged.
