J.K. Rowling describes something pretty close to what you're looking for on Pottermore. The founder of Ilvermorny (the american Hogwarts) gave birth to twins, one of which was a squib, the other a witch.

[...] the twin girls to whom Isolt had now given birth: Martha, named for James’s late mother, and Rionach, named for Isolt’s. [...] Martha, the elder of James and Isolt’s twins, was a Squib.

From this, we can assume the same kind of thing can happen in a muggle family.
