Some of the streets in Downey were named for the owners of the properties at each end. Unfortunately the streets may have been extended or truncated, so we can't tell where the ends were.
Stewart and Gray Road, Orr and Day Road, Curtis and King Road, Wiley Burke Ave.
Downey and Sanford Bridge Road
Lexington-Gallatin Road: connected the communities of Gallatin (near the intersection of Florence Av and Paramount Blvd, later absorbed by Downey) and Lexington (now El Monte)
Gallatin Road (in Downey) was originally Gallatin School House Road
Old River School Road was named for a school house near the "old river": the Rio Hondo is the old course of the San Gabriel River.
Jaboneria Road used to be Compton-Jaboneria Road. It was named for the soap factory and settlement around it, or jaboneria, set up just south of where Telegraph Road crosses the Rio Hondo, on the right bank, by Lemuel Carpenter, who eventually married one of the daughters of the Nieto family and gained control of the Santa Gertrudes rancho. Eventually he got heavily into debt, and the rancho was acquired by McFarland and Downey.
Tweedy Lane was named for one of the early settlers of Downey, George Washington Tweedy (or Tweedie). It used to be called Telegraph-Jaboneria Road, because it connected Telegraph Road with the site of Carpenter's jaboneria. There is also a Tweedy Blvd in South Gate.
Passons Blvd was named for Oliver Perry Passons, from Tennessee, through Texas, began growing walnuts on the Santa Gertrudes rancho.
