History

“Roslyn received its name from Old Roslyn, which was a post office and trading point established in 1882. H.H. Russell, the first postmaster, took the name Roslyn from his native city in Scotland.” Another source states the name Roslyn is an amalgamation of Rosholt and Lynn, the names of two lakes near the town site.

“In 1914, the Soo Line Railroad (Fairmount and Veblen Railway) was being built in the area. In order to secure the line for the community, settlers adjoining the proposed line raised $60,000. The coming of the railroad led to the selection of a new town site. On August 17, 1914, the New Roslyn was plotted and Main Street was established.” Old Roslyn was eventually abandoned.
