This is Gillian Owens from the movie Practical Magic. She'll have been around in town for three years now and runs Garden of Eve (a makeup and specialty store). You'll find a number of interesting concoctions there that she specializes in, as well as any herbs and other things that might be needed for spells. She's a witch, misses her sister, aunts and nieces terribly but has adjusted to being around as best she can.
