The focus of the book is the history of the Sacred Heart of Jesus Roman Catholic Parish and Sacred Heart Church in Montegut, Louisiana. The book follows the church-parish boundaries, including the term of each priest, and with the creation of each new parish out of Sacred Heart, St. Ann (1908), St. Joseph (1948), and St. Charles Borromeo (1971), the focus continues with the Priests of Sacred Heart. However, the book could not reflect Sacred Heart without writing about Montegut, Bourg, Little Caillou, and Pointe aux Chenes. The church has given us important roots, binding us as a church and community family, sticking us to this small place, Montegut. Sacred Heart Parish predates Sacred Heart Church by over thirty years. Pere Menard blessed the first dedicated chapel built on Dugas property at St. John the Baptist in le Terrebonne in November 1859. Sacred Heart of Jesus Church marks its founding as the creation of the parish by the Diocese of New Orleans in November 9, 1864.

Descendants of Pierre Baillo who married Catherine Poisot (Poissot) in in New Orleans in 1763.
