History
Around 1768, William Armstrong constructed a grist mill there, which remained for more than a century.  A second grist mill was constructed in Paulina in 1783 by Peter B. Shafer.  That mill was later used as an axe-helve factory and saw mill.

By 1851, Paulina had a post office, and by 1882 the population was 110.  In 1890, a grist mill was still located there.

Today
The Paulinskill Valley Trail, a  long recreational rail trail following the former route of the New York, Susquehanna and Western Railway, passes through Paulina.
