Looking for information on surname ORNELAS

Hello everyone.
MY name is Piero Ornelas, and I am tracing my family's surname to, and before it was present in San De Los Lagos. (Referred to after this, as "SJDLL) The relatives I am positive about are as follows.
This is my first attempt at this research, and I am concerned that with one mistake, I may get everything before my great grandfather wrong, and I have heard that there are several "Ornelas" families in SJDLL, who were all related. If you have any information or corrections I would welcome them! thanks!
I am very interested in if this nis true that much of our Surname is actually Portuguese and not Spanish of origin. I was surprised!
Any help or clarifications great appreciated! Thanks!
