Almost certainly named for Clarence Casper Cummings (1881-1968) as his parents George and Sacramenta owned the land on which Clarence Street was laid out in 1894. (See Cummings Street for more on the family.) Clarence was born and raised in Boyle Heights, one of six surviving Cummings children. As his family owned significant land and livestock outside of Tehachapi, Kern County, they were all living there full-time in 1903 – the year George perished in a hotel fire. A couple of brothers eventually went back to Los Angeles, but Clarence stayed on, tending to the Cummings cattle and raising chickens. He never married and lived with his older brother Edward and family.
