#primroseleaf

Spottedleaf is Catherine of Aragon. In the song, Catherine says "My loyalty is to the Vatican", so she's religious based, and Spottedleaf whole job is also religious based.

Quince is Anne Boleyn. "I broke England from the Church". Replace "England" with "Thistleclaw" and "Church" with "ThunderClan/Warrior Code/ect/"

Snowfur is Jane Seymour. "Only one he truly loved". "When my son was newly born, I died" <-RIGHT ON THE MONEY!

Grasswhisker is Anna of Cleaves. "But I didn't look as good as I did in my pic". Didn't turn out as "pretty" as Thistlestar thought she'd be.

Primroseleaf is Katherine Howard. Now, this is the one and only place where it gets iffy, because Katherine lost her head for promiscuity and Primroseleaf does not do that. So, you could think of it as a type of rebelliousness on Katherine's part, and Primrose is a literal Rebel.

And finally.

Feathertail is Catherine Parr. "I'm the survivor". Feathertail is the only "love interest" of Thistlestar who managed to avoid his advances.

and "I becha you wanna know how she got this far, hey!" :D
