John Lindsey Morrison arrived in Oregon Country in 1842 along with other famous Oregon pioneers Medorem Crawford, Asa Lovejoy, and Sidney Moss, in the same wagon train. Morrison built the home of Francis Pettygrove in early Portland, Oregon, in 1846. The street on which Pettygrove's house was located was named in honor of Morrison. The first Morrison Street Bridge, crossing the Willamette River into East Portland, has been said to be named after Morrison, but alternatively it has been stated that the bridge simply took the name of the street that had been named for Morrison.
