The rest of my ancestry is Irish, Scottish, Alsatian (French/German) and a sliver of Hungarian. None of the people in my family seem to have interest in working on that. I would imagine that Alsatian might be tough because over the centuries it kept being bounced back and forth between the French and the Germans.
Sufficiently high ranked Huguenots took pains to OBSCURE their trail out of the murderous hands of their close cousin, the King of France.
