Over the past couple of years, Findmypast.com has negotiated and established a relationship with the Catholic Church Diocese on the east coast of the United States to digitize and make available the parish records beginning in the 1600s. These are records that have previously never been easily accessed. This is not just another set of records to look at. If you have ancestors in America who were Catholic, this may be the first time you could find birth, marriage, and death records for them without going directly to the Diocese and Parishes.
Please be aware that these records are now beginning to be available online from Findmypast.com and completely searchable. Think of your Irish immigrant ancestors and those from any other country where the Catholic Church had members.
