Marriages (1922 – 1931) | ♦ | Burials (1914 – 1956)


Frequent flooding of the Mississippi River at East Carondelet forced the relocation in 1914 of the parish then called St. Joseph (1890). The congregation was a mission church of Holy Family Church in Cahokia. The new church and parish was called Sacred Heart in Diocese of Belleville; a second church was built in 1989. In 1999 the parish again became ministered by the priest residing at Holy Family. Today (2021) Sacred Heart parish is partnered with Immaculate Conception, Columbia. Sacred Heart Parish priests (1914–1990) were Rev. John Wiemar, Rev. Bernard Moorman, Rev. Patrick Slattery, Rev. Edmund A. Lugge, Rev. Meinard Dunn, Rev. Joseph Hays, Rev. Robert Keating, Rev. Lloyd Misho, Rev. George Mauck, and Rev. Emil Maziarz. The parish operated a school from 1923 to 1971.
