Yesterday while I was in the Irish Genealogical Society Intl (IGSI) office at the MGS library, I saw again several binders labelled "St. Patrick's Roman Catholic Church, LaSalle, Illinois."  I'm sure these records are available elsewhere, but blog readers should know baptism/marriage/death records from St. Patrick's are available through IGSI for the following time periods:

Baptism:        1859-1862       1862-1869         1870-1879

Marriage:      1833-1855        1856-1901        1902-1926

Death:            1838-1858       1859-1882         1908-1925 

The binders can be found in the MGS library catalog as items K059, K060 and K061; however, an IGSI member must be present when the records are searched.
