It's only thanks to a great Swiss WIKItreer Sam Zschokke that I know I HAVE an ancestor with a Flügiker name.... but then checking DNA cousins at Ancestry, MyH, 23&me etc I discover relatives with so many different ways to spell this. With my line I have NO one with this last name to put up.... Just noticed that on a WIKI search each of these strange variations has a different clump to names. One can't expect German language WIKItreers to guess every possible way English language folks will have changed the original name. I guess I'm just saying I you don't know exact dates of birth (where WIKI will find other similar names) Americans should experiment with the names they're looking for. c before k, n before gs probably added to the original. Umlauts taken out, i & e might have been u's etc.
