I am currently in the process of researching my gggrandfather, Juan Lorenzo De Herrera, and family.He married to Pablita Romero,and had son's Jose Alcario, Miguel Antonio (married Sophia Lucero), Melquiades, and Cresencio. My ggrandfather(Jose Alcario) migrated into So. Colorado(Antonito area)in late 1700's, from No. New Mexico. Any connection, maybe? I'd like to hear from you, or any one who has any information on this lineage.
