All we know is that her mom was, but other than that, the generations were lost. So technically, no one knows
Spottedpelt was the daughter of Birdflight and Cloudstar of SkyClan. Her brother was Gorseclaw. When SkyClan was forced to leave the forest Birdflight and Spottedkit and Gorsekit stayed behind and lived in ThunderClan. Spottedpelt is related to Spottedleaf and Gorseclaw is related to Tigerstar.
Tigerclaw's ancestor is an ancestor of Skyclan, Gorseclaw, who is Cloudstar and Birdflight's son. And Spottedleaf is related to another ancestor of SkyClan, Spottedpelt, who is the sibling of Gorseclaw.
Cloudstar of SkyClan? His kits were Spottedpelt and Gorseclaw, raised and born in ThunderClan. They bear striking resemblances to Spottedleaf and Tigerstar, so the latter are part-SkyClan.
Because she's related to Spottedpelt and Gorseclaw of ThunderClan, whose mother is Birdflight. Birdflight's mate is Cloudstar, the former leader of SkyClan. Birdflight, Spottedpelt, and Gorseclaw, (then Spottedkit and Gorsekit,) came to ThunderClan on account of Kestrelflight, the former ThunderClan medicine cat, because Spottedkit and Gorsekit were to young to travel. They grew up in ThunderClan, although they were really SkyClan cats. ^ This, though Spottedleaf is not half-SkyClan, but rather only distantly related to some of the original SkyClan cats over many, many generations.
At first Firestar loves Spottedleaf, but then Spottedleaf dies, so he starts liking Sandstorm. In Firestar's quest Sandstorm thinks she is only second best a backup. But then Firestar says that Sandstorm will always be his number 1 love. They then have two kits Squirrelflight and Leafpool. And Firestar will probably love Sandstorm in Starclan much,not Spottedleaf.

No, Spottedleaf did not have any kits in the Warriors series.
Featherwhisker was ThunderClan's medicine cat before Spottedleaf. He was also Spottedleaf's mentor.
Firestar. It said it in the third Warrior series when Jaypaw noticed that she loved Firestar! It is also mentioned in Firestar's Quest that Spottedleaf loved him.
Yes you can see that she does in Spottedleaf's Honest Answer and in Firestar's Quest.
Spottedleaf is a character from the Warriors series by Erin Hunter. Many fans of the series appreciate Spottedleaf for her kindness, wisdom, and strong connection with Fireheart (later Firestar). However, opinions on Spottedleaf can vary among readers.
