Can anybody explain "Sukob sa Patay" 2 me? Does it only involve immediate members of the family of the couple?

I'm getting married this coming December 2008. My grandmother died just this morning, and we are deeply saddened by this, but my fiance and I have been planning our wedding since last year and all of our wedding suppliers have all been booked and paid for. Some of our relatives wants us to postpone the wedding for a year since "Sukob daw sa Patay". But a friend told me that "Sukob" only involves immediate members of the family. Could anyone help me please? We don't want to postpone our wedding because it's too much hle and we can't afford to lose any more money (since canceling from some of our suppliers will require additional payments). Everything have been laid out already, our new house is under renovation, we have made reservations and bookings for our honeymoon, and all the guests including the ones from abroad have made necessary reservations and booking via planes and hotels. So it'll all be very difficult for us to adjust. And Is there any way to counter-act this curse?
