Buckle up, buttercups and be prepared to argue with me:-)
50) Allison (played by Vinessa Shaw) from Hocus Pocus was the perfect teen foil for the Sanderson Sisters. Smart and badass, she saved the heroes:)
49) Tabitha Stevens - Television - Tabitha starring Lisa Hartman from, the 1977 spin-off of Bewitched. HUGE flop. Please just watch it for research!
48) Bayonetta - Video Game - Bayonetta is one of only two surviving Umbran Witches, along with being the child of a Witch and a Lumen Sage. From SEGA and also Super Smash Bros. on Wii. Thanks, @wikipedia for a better bio than I wrote.

44) Katrina Crane (Sleepy Hollow)
42) Queen Bavmorda (Willow)
