Tlajomulco? & Guadalajara trip

Happy New Year to all Nuestros Ranchos Researchers.
I am excited that I will be traveling to Mexico in March
and was hoping to do some research on the family of
Dr. Jesus Sanchez Guerrero, born in Guadalajara in 1874 and his son,
Dr. Francisco Sanchez Flores, who was born in Tlajomulco in 1910.

Unfortunately, my traveling companion now thinks it would
be too dangerous for two women to go to Tlajomulco alone, so I hope
NR members can let me know if this would be unsafe for us to do. Here
in the US we hear much about the drug cartel violence but I haven't
heard of problems in this particular area. If we stay in Guadalajara,
can anyone suggest which resources would be best to seek out in my
limited time of 5 days in Guadalajara. Also, Can you tell me what the
best way would be to travel from Guadalajara and how long it would take
to get to Tlajomulco?

I would appreciate any advice and/or guidance you can give me.
