About the Thérien surname
The surname Thérien has an onomastic interpretation that still needs to be placed in the history of each family line. The form of Thérien is compatible with French surname tradition. It may derive from an old given name, a place, a nickname, an occupation, or a regional variant; the historical form of the family line is needed to distinguish between these possibilities. Etymology can clarify how the surname formed, while the earliest records remain necessary to connect that explanation with a specific family line. Thérien contains one or more diacritics in its canonical spelling. Historical or normalized indexes may omit them, which is useful to keep in mind during genealogical research. In the normalization used for some LAFRANCE searches, the surname is also matched through the form “therien”; this search variant can be useful when accents, spaces, or punctuation differ.
