In the stockton City Directory 1937, it has on page 47:
Bowerman Louis S. Rev (Flora E) h 1115 N Edison St
above him is:
Bowerman Frances prof Coll of the Pac r 1115 N. Edison St.
p.s. Coll of the Pac is College of the Pacific which today is called University of the Pacific, Stockton.
My suggestion is to ask San Joaquin County Genealogical Societyhttp://www.rootsweb.ancestry.com/~sjgs/http://www.rootsweb.ancestry.com/~sjgs/under Queries under link Melinda....and have her go to Cesar Chevez Public Library, Stockton and look at that "era" of City Directories to determine the exact years he was in Stockton.Melinda an her husband Charlie go to that library all the time for researching for others. That library has all the City Directories.
Good luck. I only have the 1937 City Directory at home and none of the others before he died.
