I am currently reviewing St. John the Baptist Roman Catholic and St Michaels Roman Catholic Church Records in Winfield and Wheaton Illinois U.S., Catholic Diocese of Joliet, Sacramental Records, 1800-1976. They have been scanned and are now posted on Ancestry.com. If you have a public library card and your library subscribes you can view the records via a library computer or you can pay for a subscription to Ancestry and view from home.
The sacramental records are true genealogical gold mines. They also provide proof as a primary source document of your ancestors birth, death, marrage, confirmation and baptism.
Here is a sample record of a record I located and downloaded. This is Casper Schlick’s burial record. He was buried in 1895. He is buried at St. Michael Catholic Cemetery in Wheaton DuPage County Illinois. He was the original Schlick that settled in DuPage County.
Here is the full page where the above record appears.
