What historical names suit an English Mastiff?

Naming Tips for Mastiff
✓ Match the name to the breed personality
Mastiff dogs have a distinct look and temperament — pick a name that reflects that energy.
✓ 1–2 syllable names train best
Short names are easier for dogs to learn. 'Max' responds faster than 'Maximilian'.
✓ Avoid command conflicts
Don't pick names that sound like 'No', 'Sit', 'Stay', or 'Down'.
✓ Test it at the dog park
Say 'Come here, [name]!' out loud 5 times. Does it feel natural to call out?
