Gutierrez Alvarez Casillas Cruz Intro

I am  trying to research my grandfather Gabino Gutierrez.  He was born in Valle
de Guadalupe, Jalisco, Mexico about 1889.  He migrated to the United States
about 1907, living in Ohio.  He married and had three children, my mother being
one.  My grandparents divorced about 1924 and he returned to Mexico, marrying a
Casillasand having two sons(Juan and Benjamin).  She died and he married her
younger sister Cecilla Casillas and had one son(Manual). My grandfather died
somewhere between 1968 and 1972.  I traveled to Mexico with my family  in 1964
to meet my grandfather  and Cecilla.  I have been trying to find if he has any
relatives still living and his history.  I have found some in Family Search, but
cannot tie all ends.  I see where he crossed the border in 1940 to visit a
sister in Los Angles.  I found her in the 1930 censuswith their parents living
with her.  I also found where his mother died in Los Angles and I know it is her
as it was stated her mother's maiden namewas Cruz and all the dates matched. 
But have not been able to see his sister's birth or any records. Any help would
be greatly appreciated. I am including link
