My wife's great-grandfather was named Rafael Tijerina. His father was Francisco Tijerina, and his mother was Luisa (Morgan) Tijerina. He married Hetrus(?) Rodriguez and had one daughter with her in 1922 in San Antonio, TX. She is my wife's grandmother. If these Tijerinas are part of the same family you're researching, please let me know. Thanks. I hope this is some help.
