I think you mean Sassoferrato rather than Sassaferrato. There are Pecci and Andreoli living in Sassoferrato still.
Original vital records for Sassoferrato (Ancona Province) are available on microfilm through Family History Centers worldwide. The records go back to 1866, so you should be able to find records for your grandparents.
These old records can be difficult to decipher. For help, I highly recommend "Discovering Your Italian Ancestors" by Lynn Nelson. This book was written to assist researchers using the microfilmed records. You can view some sample pages at Amazon.com.
