My original comment wasn’t really thought through to be honest – I was just looking for examples of roads in that area being named after people.

The Victoria County History says:
‘The next portion, Barnard Street, had at its east end the site of the medieval Barnwell’s Cross, possibly named after the family called de Bernewell’

….so the Cross is named after the de Bernewells but not Barnard Street.

I have a book called Wiltshire Place-Names which muddies the wateres slightly:
‘Barnard Street originally led to Barnards Cross and in 1428 was called Bernewellcros’

I *think* that this may have what made me conflate the names Bernewell and Barnard – but on the basis of what’s in the text this is a mistake.

I can’t find a section of the site here for road/street names beginning with B, so I’m posting re this bit of the street instead.

In the post here about Love Street, it says:

“In comparison it’s easy to find Richard Payne (Payne’s Hill), the de Bernewell family (Barnard Street) or Christopher Eyre (Eyres Way)”

I’m wondering whether anyone can tell me how/why the association between the de Bernwell surname and the Barnard street name has been made — since Barnard is itself a name with roots in the area, I might have thought the street was named directly for that surname. It’s of personal interest to me so I’d be very grateful if anyone could inform me!
