Celaya archives and Centeno

I've been searching the Celaya, Sagrario images, and found the following: "En los dias del mes de agosto de mil seis cientos cuarenta y siete anos baptice puse oleo y _______ a Diego hijo de Diego Martin y de Ana Madalena naturales de la labor de Diego Centeno. ...." What I need to know is what does the term "naturales de la labor de" mean? I'm looking for Diego Centeno's descendents in Celaya, but am not sure if I found something of value or not?....

Thanks for your help
