Last names Guadalajara/Chia/Haro

Hi everyone i was wondering if anyone knew where the families with the last name Guadalajara and chia came from. I found that some of my ancestors at the beginning of the 1700's had these last names.

Also around the same time my family on my Haro side came from guadalajara and i was just wondering if they are the same Haros from Tlaltenango but cant find anything on them. My ancestor is Francisco Xavier de Haro.

I apreciate any help
