Louisiana Creole people
Evangeline Parish was formed out of the northwestern part of St. Landry Parish in 1910, and is therefore, a former part of the old Poste des Opelousas territory. Most of this region's population was a direct result of the North American Creole & Métis influx of 1763, the result of the end of the French & Indian War which saw former French colonial settlements from as far away as "Upper Louisiana" (Great Lakes region, Indiana, Illinois) to "Lower Louisiana's" (Illinois, Arkansas, Louisiana, Mississippi and Alabama), ceded to British America. 
The majority of these French Creoles and Métis peoples chose to leave their former homes electing to head for the only 'French' exempted settlement area in Lower Louisiana, the "Territory of Orleans" or the modern State of Louisiana.
These Creoles and Métis families generally did not remain in New Orleans and opted for settlement in the northwestern "Creole parishes" of higher ground. This area reaches upwards to Pointe Coupee, St. Landry, Avoyelles and what became Evangeline Parish in 1910. Along with these diverse Métis & Creole families came West Indian slaves (Caribbean people).
