Demon Witch Child. 1975.
A young girl becomes possessed by a witch, who wants to use her body for revenge.
Thanks to Treb for helping us find another Exorcist movie rip-off, to be honest this wasn't too bad, a girl being possessed by a witch and not some demonic demon or Satan is something different, a priest being chased against his wishes and being told he is well hung was a bit of a laugh. This was done on a small budget so don't expect any great special effects but i'm pretty sure I saw about strands of string in one certain scene.
