In "Cold Iron" in Rewards and Fairies, Puck says that:
 
"...memory and remembrance between whiles I'll keep where old Billy Trott kept
his night-lines - and that's where he could draw 'em up and hide 'em at need..."
 
Can anyone identify 'Billy Trott', or was he an invention of RK's ?
 
Most grateful for any thoughts.
 
Good wishes to all
