I wasn't sure if you knew what Tourniquet meant. So here is the dictionary term. TOURNIQUET: a device (as a band of rubber) that checks bleeding or blood flow by compressing blood vessels.
As far as names go, I really love Turn Of The (Or A) Century & Return of The Giant. Here are some of my suggestions;
Midevil (meaning throughout the lines)
Laced Tourniquet (grandmother is celtic lace)
Deadwood's Returning Giant (grandfather is deadwood's chosen sun)
Probably Brazen (grandmother is probably perfect)
Brazen It Out (means: to face with defiance or impudence)
Anyways, let me know what division you want the foal in and I will look for pictures. :D
