Hi Paul.
I used old street directories and it told me that it was on Map H6
although I could have used Jon Small's map of Pubs in Northampton
town if I could have found it.

As to evacuees I would image the school took them in.
Maybe asking the Northants Record Office if any records survive
might be something to keep in mind.
There were numerous Churches of different religions in the
centre of the Town of Northampton you are asking about.
Would he have gone to Church in Queensgrove Meth, if he was a
non-conformist then maybe yes.
All the best with linking up to the Harrison family.
