Leafpool is the mother of Hollyleaf, Lionblaze and Jayfeather.
Assuming that you are talking about Squirrelflight's big lie, Squirrelflight lied to protect Leafpool as well as Jayfeather, Lionblaze, and Hollyleaf from the truth.

Leafpool's kits are Jayfeather, Hollyleaf, and Lionblaze. They are born to her and Crowfeather, but are raised as Squirrelflight's kits to keep their true parentage a secret. Each kit plays a significant role in the later story arcs of the Warriors series.
Leafpool is the real mother of Jayfeather, Lionblaze, and Hollyleaf. She gave birth to them, but due to the circumstances of their birth, they were raised believing another queen, Squirrelflight, was their mother.
Sort of but it is confusing. But this could change because Brambleclaw and Squirrelflight are not mates anymore. Leafpool is Jayfeather, Hollyleaf, and Lionblazes's mother. Squirrelflight is Leafpool's sister. Brambleclaw is (well was) Squirrelflight's mate. Brambleclaw's father is Tigerstar. Mothwing's father is Tigerstar. So they are sort of related but barely.
Squirrelflight kept a lot of secrets but her most extreme is that Lionblaze, Jayfeather, and Hollyleaf are not her kits. They are Leafpool's and the father is Crowfeather.
