US Cajun claims to citizenship under C-3

[athanwago]

Hello,

I am of Cajun (Louisiana) descent, and I can prove my family line back to Nova Scotia and Quebec as early as the 1600s; however, my ancestors were expelled during the great expulsion in the 1700s. Has anyone heard of a successful claim to citizenship through the Cajun / Acadian line? We are talking many, many generations (6 to 7).

Thanks in advance.
