Ferncloud x Dustpelt (Dustpelt is Ferncloud's uncle)
Snowbush x Lilyheart (Snowbush's mom is Brightheart, whose brother is Brackenfur, whose daughter is Lilyheart)
Patchpelt x Willowpelt (the Erins have said that these are Graystripes parents. Problem is though. THEY ARE SIBLINGS. From different litters... BUT STILL THAT IS SO WRONG.)
