I am helping my cousin with her tree. Do you have a baptism for Sebastiana Silva - daughter of Jose Nicasio Silva (b. 1849) and Eulalia Ponce?
Also, I read that you went to the San Fermin de Panuco church. Would you be willing to share a photo or two via email. I would not be posting it to any website. I thought I might include it in information I snail mail to my cousin. It's easier for her just to have information printed out.
Another branch of her tree has Sifuentes family from that area. I have found most of that information.
