Rank the Germanic admixture
Inspired by the 'who are the least Slavic Slavs' thread, rank these traditional Germanic-speakers by their Germanic admixture from least to most, in your opinion. Or at least the top 5 least Germanic admixed. I chose groups that are clearly most mixed with non-Germanic people.
Alsatians
Austrians
East Germans
Eastern/Lowland Scottish (traditional Scots speakers)
English
Flemish
South Dutch
South Germans
Swiss Germans
Western Germans (Rhinelanders)
You can include other minor Germanic groups in the ranking if you want: Afrikaners, Amish, PA Dutch, Danube/Banat Swabians, Volga Germans, Baltic Germans etc, but many of them I know little about.
