Remember the old discussions on where names came from. Someone brought up they'd never heard of Kerr, and others pointed out the name was familiar from home canning. In fact, I have a Kerr jar in my house. Underneath the embossed script "Kerr" is the phrase "Wide-mouth Mason jar".

I just recalled that one of the hiking tours I did in Ireland was down the "Kerry Way" (unless it's a different spelling - I always forget these things). There were some other interesting, Kerr-related toponyms along the way, a narrow path connecting two mountain tops called "The Knife's Edge", and "The Black Valley" just underneath. Obviously the psychic disposition responsible for these names was not unlike Avon's. (Synge claimed this was the effect of mist).
