Hi Alonso, I'm a novice at genealogy but have been successful in finding many of my Chavanas (from Lampazos, Nuevo Leon) even as far back to the very early 1800's by using http://www.familysearch.com/http://www.familysearch.com/ (Latter Day Saints) and http://18.104.22.168/cgi-bin/genealogy/logincgi?pedsrch+Englishhttp://22.214.171.124/cgi-bin/genealogy/logincgi?pedsrch+English (Kindred Konnections). Start by searching for your Dad, grandad, or any ancestor you know of. Take your time experimenting with the dates/names/options in the search questionnaire to see what works best for you. When I get organized I am going to upload my family tree to these websites. Good luck!
