This road was christened Imogene Street when Pomona was laid out in the 1870s. Eight of the town’s first streets were named after wives or other female relations of Pomona‘s founders, but I can’t suss out who this “Imogene” was. Regardless, her street was renamed Linden (after the tree) in 1917, following Louisa Street’s transformation into Locust and Elmina’s into Elm. For more on why Pomona changed its so-called “silly feminine” street names, see Main Street, formerly Elizabeth.
