Hi Holleen, Go to the edit page. I m not sure who you added wrong. But you have to start at the top. The oldest I mean. Go to the editpage and at the right there it says the brother of ........ is ......... and there is a in small letters underneath edit............ click it. Scroll to the end of the new window. There you can remove relations.
Hope that helped. Don t worry you can reset all. :)
