About 1921, several Romeo families requested of Bishop Gallagher of Detroit to allow the celebration of Mass in Romeo. Permission was granted, and Fr. Carroll came one Sunday each month from Rochester.
Since there was no church, Mass was offered in various homes and halls in the area. A church building was needed, but funds were lacking. The Catholic Extension Society loaned the parish $1000 and Romeo became a mission of Lapeer under Fr. Thomas Carey, the pastor of Immaculate Conception Church, Lapeer.
