HELP

A curator started following me and my entire family. I am not related to her. She changed my great grandmother to someone who cannot feasibly be my great grandmother. How can I delete the connection?? I've been trying to delete my "new great grandmother" but Geni won't let me. There's too many people now added to the tree for me to figure out who needs to be delete first before deleting my "new great grandmother" - HELP!!!!!!!!!!!!! This is very freaky.
