On the etymology of "folk", saying that it the word comes from Old English folc is true, although a vast over-simplification. A lot of languages share this word.
This is actually an ancient word, you can trace it back to proto-Germanic "fulka", and further to Proto-Indo-European "plh-gos" (presumably pronounced something like phulgos or pholgos, close enough to folk).
