For info prior to 1874 go to each local church. You'll need their faith, whether Catholic or non. Let them know in advance when you are coming. Each local pastor and staff are friendly folks, especially if you communicate in their language. Knowing that you are coming may require them to have an English speaker on hand. High school students are fluent in English and would be an excellent choice. After 1874 the records are in municipal government -- not everyone speaks English. In some cases they'll point you to a central archive. Happy Hunting! :-) Don
