In 1965, Sidney A Marchand Sr., compiled an index of Acadians from Ascension Parish Louisiana. His book is named An Attempt to Re-Assemble the OLD SETTLERS IN FAMILY GROUPS, published by Claitor’s Book Store in Baton Rouge, Louisiana. His work attempted to reassemble about seven hundred families of the original settlers of Ascension Parish, many of them former residents of Acadia. Mr. Marchand used records on file at the Recorder’s Office in Ascension Parish, dated 1770 to 1805, to establish his work. While there is no index to names, the entries made are in alphabetical order by Surname. Here is a list (an index) of all Theriots (with several name variants) found in Marchand’s book.
