I have ethnicity estimates from three sites, but though they differ, none tell me anything I don't know. My mother is Acadian, and I can trace both her maternal line and my grandmother's paternal line back to Port Royale. Here is what they are:
Family Tree 72% Central Europe, 18% Ireland, 8% Scandanavian, 2% Misc traces
Ancestry France 42% Eng 31%, Scot 19%, Wales 2%, Nigeria 2%, traces Africa and Indigenous Arctic
Myheritage Eng 33% Scan 31%, Iberia 16% Irish/scot 9%, Greek/south Italian 6%, Kenyan 1.6%, Ashk Jew 1.2% Sierra Leone 1%, Meso Amer and Andean 1.3%
And they keep changing.
