I am sorry that I am answering your letter so late.I just got the chance to check my e-mail.I hope this letter is not too late. My father received a phone call about 12 years ago from a man named Reyes Lopez Tijerina from Albuquerque, New Mexico.He is a political activist.He gave my dad some information on the family tree. He said that he had discovered that the Tijerinas were from Ciudad Porcuna, Espana.They were Israelites.The first Tijerinas came to America on October 19, 1510.They were Diego Tijerina and Maria Hernandez.They settled near Monterrey, Nuevo Leon and founded a little town named Tijerina. I hope that this information is useful to you.If you want to speak to the man that gave my father this information, his number is: Reyes Lopez Tijerina(505) 638-5612 This is the number he gave us, hopefully it is still useful. Please write back to me if you know any other information.
