While I’ve been able to trace the origins of other “buddy roads” like Orr and Day and Stewart and Gray, Curtis and King remains a stumper. The earliest mention I found was in a July 1st, 1931 newspaper article, which called it King and Curtis Road. (This was when Jack Branscomb owned a ranch nearby.) To add to the confusion, a 1923 tract map identified the street as Newton and Washburn Road!
