The source for Cashio Street, named in 1923, is unknown. Although there was one working class Italian family by that name living south of DTLA at that time, it’s highly unlikely that they had any connection to the anonymous developers behind this street. The true inspiration might have been an ancient English estate called Cashio (later Cassiobury) in Watford, outside of London. Sounds farfetched? Civil engineers, often called upon to name streets when developers didn’t feel like it, kept “idea files” cribbed from all manner of sources – even obscure British locales – so the old estate is a relatively credible source. For what it’s worth, Cassiobury House was still intact and somewhat well-known in 1923 although it would soon be torn down. To add to the puzzle, there was an entirely different Cashio Street in South L.A. from 1903 until 1908, when it was renamed E. 50th Place, so it may be that today’s Cashio was pulled out of some “Previously Used But Currently Available Street Names” folder.
