I was thinking something before say the generation of Hollytuft, Sorrelstripe, and Fernsong, but after Firestar, Sandstorm, Graystripe, etc. someone either in the Lionblaze, Hollyleaf, and Jayfeather generation, or right before, maybe Flametail as the father? I dunno
(I would refer to them by arcs if I actually knew them XD)
