Welcome to the Terrebonne Genealogical Society website. Our society’s interests covers not only Terrebonne Parish, but also surrounding parishes such as Assumption and Lafourche (the area known as Lafourche Interior). Be sure to check out our latest newsletter, a list of our publications, and our online data!
The Terrebonne Genealogical Society (TGS) was formed in 1972 as a part of Terrebonne Parish’s sesquicentennial celebration. It was formally organized in 1981, when a constitution was drawn up and the Society incorporated.
