Gutierrez and Camarena

I'm trying to put together a family tree about my grandmother Maria Soledad Gutierrez.....born 1901 (?) in Arandas or Guadalajara, Jalisco area.....her parent were Jose Gutierrez and Emilia Camarena...I don't have any information about them.....I don't have any further information on her family tree...it's all a mystery... my grandmother immigrated to the U.S. in 1927 (with her sister, Guadalupe)....they had two brothers, Ramon and Miguel, who stayed in Mexico....

I would like help getting information and tracing the family tree as far back as possible.

Many thanks (Muchos Gracias)...
