Cashio’s origins are unknown. The name might have been inspired by an ancient English estate called Cashio (later Cassiobury) in Watford, outside of London. Sounds farfetched? L.A. civil engineers kept “idea files” of potential street names 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 when Cashio Street was named 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.
