Sparrowtail first mated Redclaw, and they had Milkywillow and Stormclaw. Redclaw left for FireClan during the Severence, so Sparrowtail became mates with Webbedfoot, even though her and Redclaw never really "broke up", he just left. Webbedfoot and Sparrowtail had Nightwhisper, who is actually deceased. Milkywillow and an unknown tom had Goldenstrike, and yeah. Sparrowtail's the grandmother. Oh, and the reason she's in FireClan is because she moved there after the main character in kit to leader (cannonly Sliverstar) became leader, so she moved to be with Redclaw. Sorry this is a lot lol.
