This is the fifth foal of Star and Morningleaf, the secondborn of their twins.
Her name will start with "Holly" after Hollyblaze, but I have no idea what the suffix will be!
Here are some ideas I have, if you have any others, tell me in the comments.
Names
Hollysun
Hollyglade
Hollyberry
Hollybranch

Okay I have narrowed it down to Hollyberry, Hollyshine, or Hollyglade, and either her (chestnut) twin brother's name or her (buckskin) little brother's name will end in the suffix -sun
Final Name Poll!!! (though I may choose a name even if it does not receive the most votes)
Hollyshine
Hollyglade
Hollyberry
