Some years ago I had a girl stalking me. We had gone on one date, and she decided I was her destiny. She would phone my house sometimes 30 times a day and never speak unless I answered, which freaked out my roomates (female).
I eventually had Telus cut off her phone for system abuse, and had to block her email. While that was a respite, she continued to show up and contact me at work. Finally, after many months of this, I had kept track of all the encounters, and had enough info to seek and finally get a court order to keep her away from me. On the advice of the judge, she moved to the Maritimes, and thankfully I have seen hide not hair of her since.
The trick here is that it does not seem like blatant harrassment, as mine was. Harder to prove lunatic intent.
All I can suggest is document each encounter fully, so that you can use that info effectively at some point.
I somewhat doubt that sending relatives over to rough her up is as effective a strategy for a female as it is for a male...
