In 1912, Charles Guy Blackwelder (1879-1974) was working as a salesman for realtor Carlin G. Smith, who named this street that year as part of his Du Ray Place tract. Blackwelder, who went by Guy, was born and raised in central Illinois, moved to L.A. by 1906, worked in real estate and insurance, and ran a used car lot in 1917, which is when he first got married. The rest of his long life is mostly unaccounted for. He had one son, Charles Guy Blackwelder Jr., in 1932.
