The makers of The Witch were most likely influenced by this great movie
Both are set primarily in England, and later, in America. Both movies feature a lot of Old English dialogue, like "Nay", "Thee", etc. Both feature an evil witch (or Warlock, which is a male, evil witch) who kills an unbaptised child, and boils his skin so they can make a potion that will help them fly. Both are excellent horror films. I am sure the makers of The Witch were heavily influenced by this movie.
