I have been trying to research my last name and this is the most interesting information that I have come across yet. My name is Terease Sigala - I am 26 years old - and my father's name was Jose Sigala - He passed away 3 years ago in his 50's. His parents died before I was born but what I do know about them is there names were Guadalupe and Isabel (grandfather) Sigala. They and my father were from Chihuahua, Mexico also. I have no Sigala relatives besides my brother and sister. I grew up in Monrovia, California - lived in Chino, California for 10 years and now am back in Monrovia.
