There's a Harrow Green in Suffolk, and a Harrowbarrow in Cornwall. Which sound pretty old to me.

Harrow on the Hill is also quite old (I think Boadicea/ Boudicca fought the Romans round here), and in American terms not all that far from the A1. The top of the hill is quite quaint (mostly Harrow School) and with good views on a clear day, but most of modern Harrow at the bottom of the hill is not beaut.
