Vangie, This is a long overdue reply to your message! I am wondering if the Jose Tiburcio you mention is my 3X great grandfather. From census records, my 3-great grandfather Jose Tiburcio Deanda was born Sept 1829 (1900 census). You mention that the one in your line was born in 1833, however I think that it may be worth comparing notes. Do you have access to the records from Bustamante NL? I am looking for a marriage between [Jose] Tiburcio Deanda and [Maria] Petra Lopez circa 1850.
Any information that you can provide would be helpful. Thanks, James
