Who has an Order of Merlin?

I was wondering in my time travel fic who should receive an O.M. for helping defeat Voldemort, and reviewed canon for the existing recipients. Here are my findings:

• Damocles Belby: for inventing the Wolfsbane Potion
• Arcturus Black: First Class, for ‘services to the Ministry’, according to Sirius he gave them a ‘load of gold’, according to Pottermore ‘loaning the Ministry a large amount of gold’
• Albus Dumbledore: First Class for his defeat of Grindelwald
• Cornelius Fudge: First Class (according to Pottermore this was ‘self-awarded’)
• Gilderoy Lockhart: Third Class
• Peter Pettigrew: First Class
• Newt Scamander: Second Class (Fantastic Beasts Comic Relief textbook)
• (Severus Snape is offered a Second or First Class Order of Merlin for helping save the trio and aiding in Sirius’s arrest)

 

Recipients According to Secondary Canon

 

• Remus Lupin: First Class (Pottermore canon)
• Minerva McGonagall: First Class (Short Stories From Hogwarts canon)
