Posted on: Costilla County, Co Query Forum Reply Here: http://genconnect.rootsweb.com/genbbs.cgi/USA/Co/Costilla/10080 Surname: Hilerio ------------------------- I think you confused a given name with a surname. I noticed that person posted something on Hilerio Cordova. I really doubt that there are any families with the surname Hilerio in Walsenburg, CO, but who knows? I certainly am not familiar with the surname. Good luck with your search.The LDS Family History Centers in your area are a good start if you are just beginning your research. They can order microfilm from anywhere in the world. If your family was Catholic in Puerto Rico chances are that your family history is available for a little investment in time.
