Dorothy Saenz Johnston Manuel

I'm working on a tree and having a difficult time finding this woman.  Dorothy Saenz was born supposedly in California (but Mexico and Texas are possibilities) in 1907 (per marriage cert).  In 1927 she married Jesse Bell Johnston in El Paso, Texas, whom she divorced in 1932.  There is a letter from her dated 1939 from the San Francisco area where her name is Dorothy Manuel.  It is possible this Manuel husband is Leonie Manuel, married to Dorothy in 1935 in Portland, Oregon but divorced before 1940.  Leonie later married a Bonnie Bond in Louisiana and had a son in 1944 with her.  Would really appreciate some assistance with this Dorothy Saenz.
