Geni Curator Jeff, will you help me too?

My Hiram R. Rundell and his wife Mercy Wyatt currently have the same father, accidentally. I went to Relationships, but it said deleting Elnathan as Mercy's father would "split my tree". Her father is probably Nathaniel Wyatt. Can you remove Elnathan as Mercy's father? I'll go see about making my profile public. Thank you, Angela Renee Craig
