This street lies on the former Santa Eulalia ranch, supposedly named by Joseph Lancaster Brent (1826-1905), a Baltimore lawyer (and later Confederate general!) who moved to Los Angeles in 1850. It’s believed he was given the 656 acre ranch as payment for helping brother and sister Julio and Catalina Verdugo secure their title to Rancho San Rafael. George Hansen’s 1856 survey of the ranch did label it “Sa Eulalia”, owned by “Lanc. Brent”, so we know that much is true. But if it was Brent who named the ranch, it’s not clear why. He had no Eulalias in his family tree. He was Catholic, however, so he may have known about Saint Eulalia, a teenage martyr from the 4th century. (There may or may not have been two such saints.) At any rate, William Carr Belding Richardson (1815-1908) picked up the property in 1868; his granddaughter Eulalia Richardson (later Mrs. Eulalia Mitchell, 1888-1973), who would master in physics at Stanford, was born on the ranch and given its name. Eulalia Street was introduced on the 1903 Tropico Boulevard tract owned by Richardson, L.C. Brand, and E.W. Sargent.
