I have accidentally joined and merged a tree. So now my father, Roger Knight Jr. is also listed as my mother’s father. My mother’s father is Harold Gene Wells. Please assist. I am new to this and don’t k know how to undo it. Thank you. I don’t know if I merged or invited to join a tree or what. But it is inaccurate. My father, Roger A. Knight was married to Angela Dawn Wells. My maternal grandfather Harold Gene Wells was married to Patricia Sue Wren. Thank you.
