Bustamante, Cruz...

I have read several postings, but I'm new to requesting help. The Bustamante line, from Aguascalientes is the root I am researching. Cruz Bustamante B. 4-26-1882 is my Great Great Grandfather. I am having trouble finding much more than his wife and two children. I understand a member has the film for this time and place. How and who do I contact for help? I'd appreciate any help from our Nuestros Ranchos. Thank you in advance. Lupe
